## Limitations

### Textures need to be preconverted

https://feedback.vrchat.com/udon/p/whitelist-imageconversionloadimage-in-udon

The method LoadImage being unavailable through Udon, I need to preconvert the textures in advance to be able to use this

### Bones are not supported

https://feedback.vrchat.com/udon/p/whitelist-unityengineboneweight-in-udon

Udon prevents access to the members of the BoneWeight structure. Without this structure, it is impossible to represent the bones weight, making the whole armature support impossible through standard means.
