How to merge objects in a group without affecting animations

Questions

1

I have a model that has 10 groups in it, and those 10 groups have animations off, and I want to merge all the elements in the group, but it doesn’t affect the animations

I don’t think a tool exists that does this automatically. You’ll probably need to select things that are animated together, or aren’t animated at all, and merge them in Blender or a similar tool. Note that objects must share materials, or it becomes harder to merge them.

I don’t think it’s realistic without affecting the animation
