Need help rigging cases for case opening animations

My goal is to rig and animate case models so that they can be opened by players.

Ideally the animations would play in a little cutscene in front of a small set piece, kind of like Tower Defense Simulator. I’d like to animate both the camera and the case during the opening cutscene.

I modeled the cases in Blender. I rigged them with an armature and correctly painted the weights so that the model could open and close.

The issue is that my case animations in Moon Animator 2 keep breaking. All keyframes besides the camera CFrame frames are removed whenever I close and reopen studio. I’ve redone the animations twice, but my progress keeps being lost.

Original animation:

Animation after closing and opening studio:

How the model is constructed:

Renaming anything within the model also broke the animations. How can I better structure/animate these rigs so that the animations won’t break?’

Thanks so much :slight_smile:
