Thanks for the reply. Got it working! I reduced the size of it and to make it simpler, it's just a box shape now. I understand everything about the non-closed components but what is this about the component convex hull? I know the shapes need to closed, convex, and have weight, so does that button make sure they are? Also I've read that you should make your Geometry LOD bigger than the original. That doesn't make sense to me. Thanks for the advice.
