Used for mirrors. Example can be found in the SDK as VRCMirror.
Disable Pixel Lights
Disables real-time pixel shaded point and spot lighting. Pixel shaded lights will fall-back to vertex lighting when this is enabled.
Turn Off Mirror Occlusion
Disables occlusion culling on the mirror. Enable this if you see objects flickering in the mirror.
Only objects on the selected layers will be rendered in the mirror. Objects on the Water layer are never rendered in mirrors.
Rendering resolution of the mirror (per eye in VR). Auto renders at the same resolution as the user's HMD or monitor up to the maximum of 2048x2048.
The mirror will use this shader instead of the default shader if one is provided.
