Hello, I think I found a bug in the omni.anim.people extension v.0.1.9.
The extension stopped working for me after updating.
The issue seems to come from the following file:
omni.anim.people-0.1.9\omni\anim\people\scripts\commands\idle.py
After changing line 22 from
self.set_variable("Action", "None")
to
self.character.set_variable("Action", "None")
the issue was fixed.
Please fix this in the upcoming version.
