Append action question

When i append my animation to a different blend file, only the positions got animated, even tho the rotation keys are all there, i can see them in the dope sheet and graph editor.

Strange…

This is on an armature, right?

Is it basically a copy of the same armature? Same bones, same connections between them, same constraints… all the way?

yes, same armature but different file.

Here the file with the appended animation.

I figured it out. The reason the rotation didnt show is because the the appended action was animated in euler while the controls in the other file were set to quaternion. I didnt know that euler and quaternion can keyed seperately.

Is there a way in rigify to set all controls to euler at once?

Edit: found it
