I’ve noticed that when i animate the rotation of a bone in my cat rig, that when i rotate on one axis, multiple, if not all three, curves in the track view are altered. How can i get one axis manipulation to only affect one curve? ex: rotate the x gizmo, and only the x curve value change. I’ve tried setting my manipulation mode to local, parent, and gimbal, none with satisfactory results. I’ve also tried to “reset” the rotations by adding an additional euler control, in effect “zeroing” out the rotation values, and while this is handy for having the initial values of said bone defaulting to 0. It still does not affect the issue of manipulating one rotation axis in the viewport, and having multiple curves being affected in the trackview. I like to edit the keys in trackview to tweak my animations, and am finding this to be a big hindrance. Any help with this would be greatly appreciated, Thanks!

A friend of mine that works at another studio that uses cat said that making sure that checking the box, “additive to setup pose” might fix this issue. While it did in effect “zero” out the rotations, which i was very excited about, it didn’t resolve the other issue. Which essentiall means that I rotate on one axis, and multiple curves are affected simultaneously in track view. Any suggestions? Thanks!

Is this something you have found you can do when you are just using standard max bone rigs or biped?

yes, when i zero out a control on a custom max rig using max bones, i can set my translation method to gimbal, and when i rotate in gimbal mode, what axis i manipulate only affects that curve in track view. Haven’t used biped, so i’m not sure about that. I think by default, biped uses quaternion rotation system, but i think you can change that to euler, but i’m not 100% sure about that.

I’m noticing the same thing as captain max.  What is bizzare is that when you work in Gimbal, grabbing a particular axis (like rot x) will actually only affect x in the track view but the gizmo doesn’t update in the viewport.  The Gimbal gizmo stays aligned to the world.  I really hope that Autodesk addresses this issue, because animating in Local space is deceiving.  Any updates on this would be awesome.
