I have a waving animation which I’m trying to edit. So I duplicate the clip (.anim file) so I have a non read-only clip I can edit in Unity.
I edit some keyframes on the arms to make them stick out more so they avoid clipping through the waist - however I notice a flicker right at the end of the loop. On investigating the frame further, I noticed that the Y rotation for the arms was returning NaN, making the arms dissappear on that frame.
I tried deleting the last keyframe (the one which was returning NaN) and the problem ocurred on the “next” keyframe -ie what was the second to last (and now last) keyframe. It always occurs on the last keyframe on the anim clip.
I only moved the frames a little bit - there are no crazy jags or spikes in the anim curve. I can’t think whats causing this and would really appreciate any advice - it would really help my workflow to be able to edit anim clips in Unity.
