Baking Animation - Rotation Problems

[Anonymous]

Hello there,

I'm using maya 2016.

I have some issues with the bake animation. I have a scene with some constrains and when I bake a joint (to eliminate constrains) my rotation curves are kind of weird. On some parts of time line my rotations keys pops up. My joint is part of a hierarchy. I think is because of gimbal lock or something on relation to it. I couldn't keep this curves like that because of the next step of work. I need my in betweens working well.
I've tried to chance the Rotate Order and it doesn't work for me. I couldn't correct it manually, is a long animation and it will not be 100% correct if I do that. I hope there is some setting on the Bake Animation Options that will help me doing it.
I've founded a guy over the internet that had the same problem as mine. Here is the link: http://community.foundry.com/discuss/topic/77349

Here is an imagem of my curves.

Thank you.

Hi, 

I see this question did not get too many replies, so let me share my trick:
after I bake animation (usually for game), I change the framerate to 60 (from, let's say 25), then the problematic rotations become easily visible, because of the interpolation (otherwise I need to check my many joints one by one).

When I come accross a "twich" in the rotation, I select the curves in the graph editor, and press Curves/Euler filter (in Maya 2018).

This usually does the work, as it recalculates the curves, although it might not always be 100% perfect. 

I hope this helps (maybe others).
