I don't see a method called setToSetupPose on any of the objects in my Unity project.

I have problems with the way we switch animations, so if an animation doesn't set keyframes at the beginning with get bones staying set with whatever was last in the previous animation. I can't ask my animator to go back and put a keyframe on every animation and re-export everything. This seems like the perfect fix, but it doesn't seem to be available. Is this just an oversight or am I looking in the wrong place?

Any help would be appreciated.
