How to get started in VR development

See also: Developer Resource

This page serves as a comprehensive starting point for new developers to find resources needed for learning to create virtual reality experiences in 2024-2025.

Introduction

For aspiring VR developers in 2024-2025, the barrier to entry has never been lower. You can start building VR experiences with completely free tools (Unity Personal, Unreal Engine, or Godot), a $299 Meta Quest 3S headset, and free learning resources. The industry has consolidated around the OpenXR standard, meaning you can develop once and deploy to multiple VR platforms. Unity dominates VR development (68% of XR developers use it), but Unreal Engine offers superior graphics for high-end experiences. Mobile VR (Google Cardboard, Gear VR) is completely dead—standalone VR headsets like Meta Quest have replaced it entirely.

The VR development landscape in 2024-2025 is characterized by three major trends: OpenXR standardization enabling true cross-platform development, the dominance of Meta Quest in the consumer market (75% market share with 20+ million Quest 2 users), and the emergence of mixed reality features blurring the lines between VR and AR. Whether you're building games, training simulations, architectural visualizations, or social experiences, the tools and platforms available today make it possible to create professional VR content as an indie developer or small studio.

1. Understanding Current VR Hardware

The VR hardware market has matured significantly, with clear winners emerging in each category. Standalone VR headsets have become the primary development target, combining ease of use with sufficient performance for most applications. PC VR remains relevant for high-end experiences, while mobile VR has been completely abandoned by major manufacturers.

Standalone VR Headsets

Meta Quest 3S

Meta Quest 3S represents the best entry point for VR development in 2024-2025. Priced at $299 (128GB) or $399 (256GB), it offers the same Snapdragon XR2 Gen 2 processor as its premium sibling while maintaining access to the full Quest ecosystem. With 1832 x 1920 pixels per eye, 90Hz refresh rate (up to 120Hz), and full-color passthrough cameras for mixed reality development, it provides everything needed to learn VR development without breaking the bank. The device works both as a standalone headset and can connect to a PC via Quest Link for testing PCVR applications.

Meta Quest 3

Meta Quest 3 ($499 for 512GB) offers superior optics with pancake lenses and higher resolution (2064 x 2208 per eye) but uses the same processor, ensuring full compatibility between devices. This makes the Quest 3S ideal for beginners while the Quest 3 suits developers who want better visual fidelity for testing. Both headsets support hand tracking, controller input, Unity and Unreal Engine development, and WebXR-enabled browsers.

Pico 4 Ultra

Pico 4 Ultra (£529 in UK/EU, not available in US) offers an alternative with 12GB RAM (more than Quest 3's 8GB), 2160 x 2160 per eye, and Wi-Fi 7 support. It works standalone or connects to PC via PICO Connect for SteamVR compatibility. The device supports OpenXR, hand tracking, and optional motion trackers for full-body tracking. However, geographic limitations make Meta Quest the safer choice for most developers.

PC VR Headsets

HTC Vive Focus Vision

HTC Vive Focus Vision ($999) bridges standalone and PC VR with a hybrid design, offering 2448 x 2448 per eye (5K resolution), 120° FOV, and built-in eye tracking with foveated rendering. The device includes auto-IPD adjustment, hot-swappable batteries, and 26-point precision hand tracking, making it suitable for professional development and enterprise applications.

PlayStation VR2

PlayStation VR2 ($549, plus $59 PC adapter) entered PC VR compatibility in August 2024, offering 2000 x 2040 per eye on OLED displays with 90Hz/120Hz refresh rates. The device provides access to both PS5 exclusives and SteamVR libraries. However, PC functionality lacks several PS5 features: no eye tracking, HDR, headset haptics, or adaptive triggers when used with PC. This makes it best suited for developers targeting both PlayStation and PC platforms simultaneously.

Valve Index

Valve Index ($999 full kit, $499 headset only) remains available but is not recommended for new purchases in 2025. Launched in 2019, its 1440 x 1600 per eye resolution and $999 price point make it poor value compared to Quest 3, despite its industry-leading 130° FOV and excellent "Knuckles" controllers with finger tracking. A successor ("Deckard") is rumored for late 2025 but unconfirmed.

Mobile VR Status

Mobile VR is completely dead as a development platform in 2024-2025. Google Cardboard viewers are no longer officially produced (discontinued March 2021), though third-party versions exist for $5-50. The SDK was open-sourced in November 2019 but receives no active development. Google states plainly: "we're no longer actively developing the Google VR SDK." Samsung Gear VR was discontinued in 2020, and Google Daydream View ended in October 2019.

The mobile VR market has completely shifted to standalone headsets like Meta Quest and Pico, which offer superior 6DoF tracking (versus mobile VR's 3DoF), dedicated VR processors, and no phone requirement at comparable or lower prices. Do not develop for mobile VR platforms—invest in standalone VR instead.

Mixed Reality Devices

Apple Vision Pro

Apple Vision Pro ($3,499 for 256GB) represents the premium end of mixed reality, offering 23 million total pixels, micro-OLED displays, and best-in-class color passthrough quality. The device runs visionOS with native support for Swift, SwiftUI, RealityKit, and ARKit, plus Unity support and WebXR in Safari. The M2 + R1 chip combination provides exceptional performance with 12ms eye tracking latency.

However, the $3,499 price point severely limits developer adoption, and Vision Pro does not support OpenXR, requiring completely separate development from other VR platforms. Hand and eye tracking serve as primary input (no controllers), making it unsuitable for traditional VR games but excellent for enterprise applications, productivity tools, and spatial computing experiences.

Recommended Hardware for Beginners

Start with Meta Quest 3S ($299) for the optimal combination of price, capability, and ecosystem access. The device handles standalone VR development, connects to PC for testing PCVR builds, supports mixed reality features, and targets the largest VR user base. This single headset covers most development needs for beginners and indie developers.

2. Game Engines and Development Software

The game engine choice fundamentally shapes your VR development experience. All major engines support VR development in 2024-2025, but they differ significantly in learning curve, visual capabilities, and pricing models. Unity dominates the VR development landscape, but Unreal Engine and Godot offer compelling alternatives for specific use cases.

Unity: The VR Development Standard

Unity 6 (released October 17, 2024) represents the current Long Term Support release, supported through October 2026. The engine offers the most comprehensive VR platform support and the largest ecosystem of VR-specific assets, tutorials, and community resources. Unity's licensing model changed significantly in 2024: Unity Personal is completely free for projects earning up to $200,000 annually (increased from $100,000), with no mandatory splash screen in Unity 6. Unity Pro costs $2,040/year per seat. The controversial runtime fee was cancelled in September 2024.

XR Interaction Toolkit (current version 3.0.8) provides Unity's high-level, component-based interaction system for VR and AR. The toolkit includes object hover, select, and grab interactions; haptic feedback; visual feedback with tint and line rendering; canvas UI interaction; teleportation and locomotion systems; hand tracking; eye gaze support; and poke interaction for mixed reality. The system works across Meta Quest, OpenXR-compatible devices, and Windows Mixed Reality platforms.

Unity's VR template includes teleportation, snap turn mechanics, grab interactions, VR menu systems, and input mapping preconfigured for rapid prototyping. The XR Device Simulator allows VR development without a physical headset, though testing on actual hardware remains essential. Unity supports Android XR, Meta Quest, PlayStation VR2, Apple iOS and visionOS, and all OpenXR-powered headsets.

Unreal Engine: High-Fidelity VR Graphics

Unreal Engine 5.5 (latest in late 2024) provides cutting-edge graphics capabilities that make it the preferred choice for AAA VR experiences and architectural visualization. The engine is completely free for game developers earning less than $1 million USD annually. Above that threshold, Epic Games charges a 5% royalty on gross revenue (reduced to 3.5% if games launch simultaneously on Epic Games Store starting January 2025). No royalty applies to sales made through Epic Games Store. Non-game uses (film, TV, architecture) require a $1,850/year seat-based subscription for companies making over $1 million annually.

Nanite and Lumen represent Unreal's technical advantages: Nanite provides virtualized geometry for highly detailed environments without traditional polygon count limitations, while Lumen delivers dynamic global illumination and reflections with real-time ray tracing. These features enable visual fidelity that exceeds what's achievable in Unity without extensive custom work. However, VR optimization remains crucial—mobile VR platforms may require disabling these features for performance.

The built-in VR Template includes teleportation locomotion, VR spectator Blueprint, common input actions for grabbing and attaching items, and compatibility with HTC Vive, Valve Index, Oculus Rift, Oculus Quest, Windows Mixed Reality, and PlayStation VR. Blueprint Visual Scripting allows rapid prototyping without C++ knowledge, making Unreal accessible to beginners despite its reputation for complexity.

For beginners, start with Blueprints rather than jumping into C++. Blueprint's node-based visual scripting removes coding barriers while teaching fundamental programming concepts. Transition to C++ later for performance-critical code once you understand VR development principles.

Godot: Open-Source Alternative

Godot 4.5 (released September 15, 2025) offers a completely free and open-source VR development option with no strings attached. Licensed under MIT, Godot imposes zero royalties or revenue caps, making it ideal for developers who want full ownership without licensing concerns. The engine has gained significant traction in the VR space with comprehensive OpenXR support built directly into Godot 4.0 and later.

Recent updates brought hand tracking via XRHandModifier3D node for cross-platform hand tracking (OpenXR and WebXR), face tracking with Unified Expressions standard support, body tracking using Humanoid Skeleton, composition layers for floating panels with sharp 2D content, scene discovery and spatial anchors for Meta Quest, enhanced foveated rendering via Variable Rate Shading, and WebXR improvements including hand tracking and MSAA.

Platform support includes Meta Quest (2, 3, Pro), Pico 4, HTC Focus 3 and XR Elite, Magic Leap 2, SteamVR headsets, and Qualcomm Spaces (Lynx R1). GDScript, Godot's Python-like scripting language, offers a gentler learning curve than C# or C++, making it excellent for beginners. The engine also supports C# for developers familiar with that language (though not yet for web exports).

Godot suits indie developers and those philosophically aligned with open-source software, but it lacks Unity's extensive asset store and Unreal's AAA graphics capabilities. For learning VR development principles without financial investment, Godot represents an excellent choice.

WebXR: Browser-Based VR Development

WebXR Device API achieved W3C Candidate Recommendation status on October 1, 2025, replacing the deprecated WebVR API that never achieved full standardization. WebXR provides a unified API for VR and AR experiences that run directly in web browsers without installation, working across desktop VR, mobile VR, and AR platforms. This enables instant access and easy sharing compared to native applications.

A-Frame (version 1.6.0 as of November 2024) offers the most accessible WebXR framework, using HTML-like markup for building 3D/VR experiences. Built on Three.js with Entity-Component-System architecture, A-Frame allows developers to create VR scenes with minimal JavaScript knowledge. The framework provides a large community, extensive component library, and excellent beginner-friendliness.

Babylon.js provides a powerful, TypeScript-native real-time 3D game engine with comprehensive WebXR support. The WebXR Experience Helper offers one-stop access to XR functionalities including gaze, teleportation, and AR features. Havok Physics engine integration and an online playground make Babylon.js ideal for developers comfortable with TypeScript who want production-ready capabilities.

Three.js remains the most popular JavaScript 3D library with built-in WebXR support, offering lower-level control and maximum flexibility compared to higher-level frameworks. React developers can use React Three Fiber, a React renderer for Three.js that enables building VR experiences using React components and modern hooks-based APIs.

Browser support spans Chrome, Microsoft Edge (Chromium-based), Firefox, and Safari (iOS) for AR. WebXR enables cross-platform deployment without platform-specific SDKs, though performance and feature sets remain limited compared to native VR applications. Use WebXR for prototypes, web experiences, lightweight applications, or when instant accessibility matters more than maximum performance.

3. Development Resources and Tools

Building VR applications requires more than just a game engine. The modern VR development stack includes official SDKs for platform-specific features, 3D modeling software for asset creation, learning resources for skill development, and audio tools for spatial sound design.

Official SDKs and Cross-Platform Standards

OpenXR

OpenXR represents the most important development in VR platform interoperability. This royalty-free, open standard from the Khronos Group provides cross-platform API access to VR and AR devices, eliminating the need for platform-specific code. OpenXR 1.1 (released April 15, 2024) consolidated widely-used extensions into the core specification, reducing fragmentation and simplifying advanced XR development.

Major platform support includes Meta Quest (full support since 2021, all new features delivered via OpenXR extensions), Microsoft (Windows Mixed Reality, HoloLens 2), Valve SteamVR, HTC Vive, Pico (OpenXR 1.1 conformant announced 2024), Google Android XR (announced December 2024), Varjo, NVIDIA CloudXR, and Qualcomm Snapdragon Spaces. Apple Vision Pro does not support OpenXR, using proprietary visionOS APIs instead.

Unity, Unreal Engine, and Godot all provide native OpenXR support through plugins or built-in systems. Developers targeting multiple VR platforms should prioritize OpenXR implementation over platform-specific SDKs whenever possible, adding platform-specific features only when necessary for functionality unavailable through OpenXR.

Meta Quest SDK

Meta Quest SDK (Meta XR Core SDK version 74+) provides the primary SDK for Quest development, with full OpenXR support now recommended. The SDK offers VR and mixed reality capabilities, Unity and Unreal Engine integration, and Meta Spatial SDK for Android-based development.

SteamVR SDK

SteamVR SDK (OpenVR) continues as the underlying API for SteamVR. The Unity plugin (version 2.8.0, updated January 17, 2024) provides SteamVR integration, though Valve has transitioned focus to OpenXR.

Learning Resources for VR Development

Spatial Audio Tools

Steam Audio

Steam Audio (version 4.6.0, released December 2024) provides the best free spatial audio solution for VR. Developed by Valve, the advanced spatial audio SDK uses physics-based sound propagation and HRTF-based binaural audio. Features include HRTF binaural rendering, physics-based sound propagation, occlusion and reverb simulation, low-latency audio for hundreds of sources, Ambisonics support, and baking for design-time optimization. The completely free and open-source SDK includes plugins for Unity, Unreal Engine, FMOD Studio, and Wwise (added in v4.6.0), plus native C++ API.

FMOD Studio

FMOD Studio by Firelight Technologies offers DAW-like workflow with timeline-based event system, real-time parameter control, adaptive music systems, 3D spatialization, and built-in event macros. The indie license is free for projects under revenue thresholds, with commercial licensing requiring contact with Firelight. FMOD's easier learning curve and intuitive interface make it ideal for indie developers and solo creators.

Wwise

Wwise by Audiokinetic represents the industry standard audio middleware used in AAA productions. The powerful Game Call system, Actor-Mixer hierarchies, advanced profiling tools, comprehensive sound propagation, and extensive documentation make it preferred for large productions. A free tier exists for indie developers under revenue limits, with commercial pricing available by contacting Audiokinetic.

For indie developers, start with Steam Audio (free) for spatial audio, adding FMOD (easier) or Wwise (more powerful) as projects grow in complexity.

4. VR Development Best Practices

Creating comfortable, intuitive VR experiences requires following established best practices that prevent motion sickness, optimize performance, and design interactions that feel natural in 3D space.

Performance Targets and Optimization

VR applications must maintain 90 FPS minimum on target hardware to prevent motion sickness and ensure comfort. Meta Quest store qualification requires 90 FPS on recommended spec machines with an absolute minimum of 45 FPS on minimum spec machines. Frame time must stay at 11.1 milliseconds or less for 90 FPS. PlayStation VR2 targets 90Hz or 120Hz refresh rates. PC VR headsets typically target 90Hz or higher.

Platform	Target FPS	Frame Time	Notes
Meta Quest 2/3/3S	90 FPS (72 FPS minimum)	11.1ms	120Hz experimental on Quest 3
PlayStation VR2	90-120 FPS	8.3-11.1ms	Both 90Hz and 120Hz modes
PC VR (Index, Vive)	90-144 FPS	6.9-11.1ms	Varies by headset
Apple Vision Pro	90-100 FPS	10-11.1ms	Adaptive refresh rate

Optimization guidelines recommend limiting to 500-1,000 draw calls per frame and maximum 1-2 million triangles/vertices per frame. Use texture compression and mipmapping universally. Limit script execution to 1-3ms per frame to avoid CPU bottlenecks. Identify whether bottlenecks are CPU or GPU-bound and optimize accordingly—CPU handles simulation logic, state management, and scene generation while GPU handles texture sampling and mesh shading.

For Unreal Engine VR, enable Mobile Multiview for standalone VR (Quest, Pico) and Instanced Stereo for PCVR. Enable Round Robin Occlusion (RRO) which alternates rendering between eyes for performance gains. Use forward shading instead of deferred rendering, and set MSAA to 4x for optimal quality/performance balance.

Unity VR optimization leverages Universal Render Pipeline (URP) which provides performance needed for mobile VR. The multi-threaded Data-Oriented Technology Stack (DOTS) enables advanced performance optimization for complex scenes.

Motion Sickness Prevention

VR motion sickness occurs primarily due to sensory conflict: eyes perceive movement while the inner ear senses stillness. Additional causes include low frame rates below 90 FPS, high latency between head movement and display update (keep under 20 milliseconds), low resolution causing eye strain, and display flickering affected by refresh rate and luminance.

Prevention strategies combine technical requirements with thoughtful design:

• Maintain consistent 90 FPS minimum without exception
• Keep latency under 20ms between head movement and display update
• Implement Field of View (FOV) reduction during movement using vignette effects that darken peripheral vision during locomotion
• Offer both teleportation and continuous locomotion options when possible
• Avoid sharp visual patterns in peripheral vision
• Use the 80/20 composition rule: 80% darker colors, 20% bright colors to reduce visual stress

Teleportation locomotion eliminates motion sickness by removing continuous movement optical flow, though it introduces higher cognitive workload. Continuous/smooth locomotion feels more natural and performs better for speed and precision tasks but can induce sickness if implemented poorly. Static reference frames (virtual cockpit, virtual nose) provide mixed results depending on users.

UI/UX Design for VR

Meta's official VR design guidelines emphasize prototype early and test frequently—2D screen design differs radically from actual VR experience. Use physical world metaphors to guide design; familiar objects don't require learning new interaction models. Support intuitive interactions where users can naturally grab objects and press buttons. Keep UI concise and unobstructive, avoiding coverage of the entire scene.

Angular scale measurement using dmm (1mm/1px at 1m distance) ensures consistent element sizing across varying distances. Safe area guidelines prevent title-text and key elements from being cut off by headset FOV limitations. Spatial design considerations require rethinking traditional UI patterns—no conventional anchor points like screen corners exist in VR.

Interaction Design Patterns

Locomotion Systems

Locomotion in 2024 shows a trend toward continuous/smooth locomotion replacing teleportation in commercial applications, though teleportation remains important for comfort-first scenarios:

• Teleportation: Eliminates optical flow and motion sickness but adds cognitive workload. Use arc trajectory visualization to show destination. Best for exposure therapy, casual exploration, and comfort-first applications.
• Continuous locomotion via joystick: Provides natural feeling with optimal speed and precision, standard in many commercial games (Half-Life: Alyx, Skyrim VR)
• Snap turn: Provides discrete rotation to avoid continuous turning discomfort, commonly paired with other locomotion
• Room-scale physical walking: Offers maximum immersion limited by tracking space; use redirected walking techniques for larger virtual spaces

Hand Tracking vs Controllers

Meta Quest 2, 3, and Pro include hand and body tracking toggleable in Movement Tracking settings; switch between controllers and hands by clicking controllers together. HTC Vive Focus 3 requires enabling in Settings > Inputs with pinch gesture for selection. Valve Index controllers feature advanced capacitive sensors for finger tracking on controllers, force sensors in grip for variable squeeze detection, and strap design allowing fully opening hands without dropping controllers.

Controllers remain dominant for precision tasks and gaming in 2024-2025, while hand tracking gains adoption for social VR, casual interactions, and accessibility. Many apps support both with seamless switching.

Grab and Manipulation

Patterns from Unity XR Interaction Toolkit include:

• Direct grab: Using sphere trace from controller position
• Distance grab: Using ray-based selection for distant objects
• Attach on grab: Where objects snap to specific attachment points
• Physics-based throwing: Combining velocity, trajectory, and release timing

5. Programming Languages for VR Development

Each game engine uses specific programming languages, and your language choice should align with your platform choice.

C# for Unity VR Development

Unity exclusively uses C# for scripting, making it the most important programming language for VR developers given Unity's 68% market share among XR developers. The official Unity Learn VR Development Pathway provides free, structured learning. Unity's Visual Scripting offers an alternative for non-programmers, enabling VR development without traditional coding.

The XR Plug-in Management system handles device support, while XR Interaction Toolkit provides high-level components. Unity's VR template includes teleport locomotion, snap turn mechanics, grab interactions, VR menu systems, and input mapping preconfigured.

C++ and Blueprints for Unreal Engine VR

Unreal Engine offers two development paths: Blueprint Visual Scripting and C++ programming. For beginners, start with Blueprints exclusively. Blueprint's node-based visual scripting eliminates code barriers while providing immediate results, easier understanding of coding principles, full VR Template availability, and transition path to C++ after mastering concepts.

The VR Template in Blueprints includes VRPawn with locomotion logic, GrabComponent for interactions, teleport and snap turn implementations, and built-in OpenXR support compatible with Meta Quest, VIVE, Valve Index, and PSVR2.

C++ becomes necessary for AAA game development, better performance optimization, and full control over engine features, but carries a harder learning curve. Industry standard AAA projects use 10% Blueprints for gameplay logic and 90% C++ for performance-critical code. Indies can succeed with primarily Blueprint-based projects, adding C++ only when performance demands it.

JavaScript/TypeScript for WebXR

WebXR development uses standard web technologies: JavaScript or TypeScript with WebGL/WebGL2 rendering. TypeScript support requires installing types via npm and importing with proper declarations.

Framework selection depends on developer background:

• A-Frame: HTML-based syntax for maximum accessibility, best for beginners
• Babylon.js: TypeScript-native with excellent WebXR Experience Helper, ideal for TypeScript developers
• Three.js: Most flexibility and control with the largest community but requires manual WebXR setup
• React-XR: Built on react-three-fiber, offers React components with modern hooks-based API, perfect for React developers

WebXR requires HTTPS (secure context) but enables deployment across desktop and mobile without app installation, instant updates, and future-proof compatibility with new hardware automatically supported.

6. Advanced Topics

Beyond basic VR development, several advanced topics enable more sophisticated experiences.

Photogrammetry and 3D Scanning

Photogrammetry converts photographs into 3D models, enabling realistic VR environments from real-world locations, authentic asset textures, architectural visualization, digital twin creation for training, and cultural preservation in VR experiences.

RealityScan

RealityScan 2.0 (rebranded from RealityCapture by Epic Games in 2024) offers professional-grade photogrammetry that's free for students, educators, and individuals/companies with annual gross revenue below $1 million USD. Features include AI-assisted background masking, visual quality inspection with heatmaps, aerial LiDAR and terrestrial data support, and orthographic projections for mapping.

Polycam

Polycam (iOS, Android, Web) provides accessible photogrammetry with LiDAR scanning support, Room Mode for floor plans, AI-based 360 capture, and seamless Unity/Unreal integration. Free plan includes 5 photogrammetry captures with up to 100 images each and 12+ export formats. Pro plan costs $17.99/month or $99.99/year.

Meshroom

Meshroom by AliceVision provides 100% free and open-source photogrammetry with node-based workflow, Structure-from-Motion and Multi-View Stereo algorithms, real-time 3D model viewing, HDR image fusion, panorama support, and plugins for Gaussian Splatting and NeRF. Requires Nvidia GPU with CUDA support recommended.

Cross-Platform VR Development with OpenXR

Developing for multiple VR platforms simultaneously maximizes audience reach. OpenXR provides the foundation for cross-platform VR, enabling single codebase deployment to Meta Quest, SteamVR, Pico, Windows Mixed Reality, HTC Vive, and most modern headsets. Apple Vision Pro remains the notable exception, requiring completely separate development using visionOS, Swift, and proprietary APIs.

Unity with XR Interaction Toolkit represents the most popular cross-platform approach (68% of XR developers use Unity). The framework provides unified VR/AR interactions across Quest, PSVR2, SteamVR, Pico, Windows MR, iOS, and Android. Native OpenXR plugin support enables single codebase building to 25+ platforms.

Cross-Platform Challenges

• Performance differences between Quest (mobile), PC VR, and PSVR2 require quality settings/LOD systems, adaptive rendering based on device capabilities, and separate optimization passes per platform
• Input differences across controllers, hand tracking, and eye tracking require using OpenXR's unified action system and abstracting input into gameplay actions
• Platform-specific features like passthrough MR (Quest/Pico) and eye tracking (PSVR2/Varjo) require designing core experiences that work everywhere while adding platform enhancements as optional features
• Store requirements vary significantly between platforms

Publishing Platforms and Distribution

Meta Quest Store

Meta Quest Store provides access to the largest VR user base (20+ million Quest 2 users, growing with Quest 3 and 3S). Submission process requires creating developer account, enabling Developer Mode on Quest, building and packaging app meeting Quest requirements, uploading via Meta Quest Developer Hub, passing Virtual Reality Check (VRC) guidelines, and waiting 1-5 days for review with 30-day waiting period for first titles.

Requirements include proper controller support, correct application manifest, correctly signed APK, 72 Hz minimum performance (90 Hz recommended), secure keystore file management, VRC compliance, and high-quality branded assets. App Lab apps merged into main Meta Horizon Store as of August 2024.

SideQuest

SideQuest serves as third-party discovery platform and official App Lab discovery channel. Less rigorous approval than main Quest Store enables experimental content distribution. 24 indie games launched from SideQuest to official Meta Store in 2023, demonstrating it as proving ground for developers.

Steam VR

Steam VR offers open PC VR publishing with $100 app deposit fee (recoupable after $1,000 gross revenue), support for Vive, Index, Rift, Windows MR, and Quest via Link, and 30% revenue share (decreasing to 25% after $10M, 20% after $50M). No mandatory quality bar makes it more open than Quest Store.

Pico Store

Pico Store provides active and growing distribution with global presence, developer support through Unity and Unreal SDKs, and OpenXR 1.1 conformance announced 2024. Strong market focus in China and Europe.

PlayStation VR2

PlayStation VR2 publishing remains challenging for indie developers, requiring Sony partnership rather than self-service like Quest or Steam. Best suited for established studios with existing portfolios or publisher relationships.

Distribution strategy recommendation: Release on Quest first (largest audience), simultaneous Steam release for PC VR players, Pico for international reach, PSVR2 only if budget allows higher production values.

7. Getting Started: Your First VR Project

The path to VR development starts with choosing your technology stack based on your goals, budget, and existing skills. For most beginners, the recommended stack is Meta Quest 3S ($299) + Unity with C# + free learning resources + Blender for 3D assets. This combination minimizes cost while targeting the largest VR user base and leveraging the most extensive learning resources.

Install Unity Hub and Unity 6, create a new project using the VR template, install XR Interaction Toolkit via Package Manager, configure your Quest 3S in Developer Mode, and connect to test builds. Follow Unity Learn's VR Development Pathway for structured education. Supplement with Valem Tutorials on YouTube for practical examples. Use XR Device Simulator when headset isn't available, but test frequently on actual hardware.

Alternative Paths

• Unreal Engine with Blueprints for superior graphics (ideal for architectural visualization)
• Godot for completely free open-source development with no licensing concerns
• WebXR with A-Frame/Babylon.js for browser-based VR accessible without installation

First Project Checklist

Focus first on:

• Maintaining 90 FPS minimum
• Implementing both teleportation and continuous locomotion with comfort options
• Designing UI that doesn't obstruct view
• Testing interaction distances and reach in VR
• Implementing hand presence with clear visual feedback

Motion comfort should never be compromised—always prioritize user comfort over ambitious features.

Community Resources

Join VR development communities on Reddit (r/virtualreality, r/Unity3D, r/unrealengine, r/oculus), Discord servers for specific engines and tools, and official forums from Meta, Unity, and Unreal. The VR development community actively helps beginners, and sharing early prototypes yields valuable feedback.

The most important step is starting. Download Unity or Unreal today, follow the official VR template tutorials, and build something simple—a room with grabbable objects, a teleportation system, or a simple VR experience. Learning VR development requires experiencing VR development.
