Hi there!
I’m trying to attach a model to a joint like it’s described here: https://docs.panda3d.org/1.10/python/programming/models-and-actors/attaching-objects-to-joints
The model is okay until an animation is started. In that moment I’m getting such an error:
Traceback (most recent call last):

I’ve looked through several similar topics, zero scales and so on, but nothing helps me. Any thoughts?
