I have an animation that I'm trying to get the correct appearances in. I have tried deleting all the top level appearances, and have even deleted all the appearances from the appearance tab of the feature manager, but a couple of my parts refuse to change into their part colors. I really don't want to animate appearances for this job. How do I get rid of the appearance the motion study has applied when it doesn't show up anywhere in the tree and is not animated in the timeline?
