I have a problem with a skinned mesh imported in Sketchfab (see image Sketchfab), there is a distortion on the mesh. In 3ds Max mesh looks normal (see image 3dsMax Full Weight Range). I reproduced the distortion effect in 3ds Max by deleting all the weights lower than 0.01 (see image 3ds Max with the problem).
The question is: does Sketchfab remove all the weights lower than 0.01? Are there any restrictions with bone’s weights range?
