The skinning is very different in Unity (2021.3.8f1) from Maya. Its rougher and I have spikes, despite ensuring that the two are matched up vertex influence wise.
At the moment I can only presume this is a bug.
Is anyone aware of any other quality settings or import settings I need to be aware of?
Is there a recommended method of bind options? It would be great if I could get a Unity developer to clarify ideal skinning solutions as in my experience of animating characters in Unity this hasn’t been documented anywhere
If there is the same problem in these programs, then most likely it is a problem of the vertices of the model, only a rework will help here, do you have a rig on the model? Try to remove it and see the changes
