I think I’ve been somewhere similar before, but I’m having difficulties figuring out how to clear all animation data in a file:
The context menu option disappears the moment I do select all…
Also, in the Data API, I don’t see animation as an option:
Apparently, there’s a “Remove Anim” command that you can use, that works on “select all” in the 3D viewport, but again, the Outliner failed me.
