It also works more or less when the Unity Editor is in Edit mode, without needing to enter Play mode. If there are world creators, avatar creators, and shader creators who would be interested in trying this, please let me know. VRChat & BIRP not required.

For posterity, this has been released here as a free product called LetMeSee (LMS). VRChat not required. This can also be used for the development of standalone content, building game levels and worlds, or simply viewing animated models in VR.

this will be a gamechanger for world development. i hate that i always have to build & start VRChat to check the scale of things

I would love to try this out!

わー！3D(VR)で動いててすごーい！☺
