To solve the problem described in the article "Fixing Descending Stairs Walk from Mixamo", I used the Mixamo Control-Rig addon. Everything is well fixed.
In the next step, I am trying to transfer the character to another file. As a result, I get a complete collapse of the system.
Is there a way to get the character back to standard bones, or is it a one way road? Blender version 3.1.2.
