Quest Content Limitations

This page will describe various limits in place for the Oculus Quest version of VRChat. These limitations are in place in the interest of performance, user safety, and discouraging malicious behavior.

Find more information about limited components on our Quest Content Optimization page.

Avatar-Specific Limitations

Although the current version of VRChat does not implement a hard limit, we may implement a hard limit for avatars based on triangle count, material counts, mesh counts, and other qualities in the future. Please keep our recommendations in mind as described in Quest Content Optimization.

Currently, if you upload an avatar or avatar world that features avatars exceeding our recommendations, that world or avatar may be removed from public access.

Shaders

VRChat on Quest only permits the shaders provided with the latest SDK on avatars. The shaders are listed below with a short description and their inputs. This list may change, and we'll announce in our patch notes when new shaders are available.

All of the shaders listed below are under VRChat/Mobile in the shader selection dialog.

For performance reasons, make sure you always enable "Enable GPU Instancing" on your materials.

Shader Name	Shader Description
Standard Lite	A "Lite" version of Unity Standard that requires less VRAM. Supports the channel mappings of Unity's Standard Metallic setup, except Alpha and Parallax. The diffuse texture is tinted by the mesh's vertex colors. You can optimize different channels by packing them into the same texture: Texture 1: Albedo (RGB) and Detail Mask(A) Texture 2: Metallic (R), Occlusion (G), and Smoothness (A) Not recommended on PC because it does not support real-time lighting.
Bumped Diffuse	Diffuse but with a normal map. The diffuse texture is tinted by the vertex colours.
Bumped Mapped Specular	Diffuse, but with a specular map (shininess) on the alpha channel. The diffuse texture is tinted by the vertex colours. Normal map also supported.
Diffuse	Just diffuse! The diffuse texture is tinted by the vertex colours.
Matcap Lit	Diffuse, but with a matcap input. Can be used to simulate a shiny metal surface. The diffuse texture is tinted by the vertex colours.
Toon Lit	Provides toon-like shading and shadows. Should be used on cartoon-like characters with flat colors. The diffuse texture is tinted by the vertex colours.
Particles/Additive	Should be used on particles. Blends using Additive mode.
Particles/Multiply	Should be used on particles. Blends using Multiply mode.
Lightmapped (Only for worlds)	A basic diffuse shader that supports lightmapping. This shader is only meant for use on worlds. It cannot be used on avatars. It does not support real-time lighting.
Skybox (Only for worlds)	This shader is an optimized skybox shader, meant for use in worlds.
Supersampled UI (Only for worlds)	An unlit shader which is is supersampled at the texture sample phase. Use with mipmapping to make in-world UI text crisp without being grainy or distracting.

Components

The following components are not supported on Android or Quest and will not work. This list may change. We'll note in the Patch Notes and updated documentation when these change.

Shader Name	Shader Description
Dynamic Bones	Completely disabled on Android and Quest. Use PhysBones instead!!
Cloth	Completely disabled on Android and Quest.
Cameras	Completely disabled for avatars on Android and Quest. Permitted for use in Worlds. Be careful with overuse.
Lights	Completely disabled for avatars on Android and Quest.
Video Players	Works with some limitations. Read more in Video Players.
Post-Processing	Post processing systems are disabled completely on Android and Quest. The GPU is not designed to handle these effects very well.
Audio Sources	Audio sources are disabled completely for avatars on Android and Quest. Audio sources consume a significant amount of CPU resources and voices have priority.
Physics Objects	Rigidbodies, colliders, and joints are disabled completely for avatars on Android and Quest. They are permitted in worlds, but you should be careful not to go overboard with them.
Particle Systems	Particles are limited heavily on avatars for Android and Quest, with settings mirroring the Avatar Particle System Limits on PC.
Constraints	Unity constraints are disabled completely for avatars on Android and Quest due to complex performance issues. Use VRChat Constraints instead. Permitted for use in Worlds. Be careful with overuse, as they impact performance more than previously thought, especially with the limited resources of Quest and mobile devices.
FinalIK	Custom FinalIK components are completely disabled for avatars on Android and Quest. FinalIK components are an unbounded source of resource usage. We do not currently plan to enable them on these platforms.
