I spoke too soon. I am able to replace a submesh and have the animations still work. Just had to modify the model properly in 3d studio max. Looks like I'll just have to modify rbody to paste all the meshes/submeshes together with LODs. I'm pretty sure this should be possible.

I didn't have that issue because we were driving the skeleton externally and used Cal3D only for skinning. So the skeletons were forced into the same position from a common external skeleton driven by our in-house animation library. That is not the most common use case, I admit. However, I believe that the synchronization could be done, but you will have manually set the position within the current animation when you switch the LOD. An on-update callback could do that. > I think we discussed this before, but I thought you replaced all the > different submeshes with LODs; not the whole model. No, the whole model. It will not work with submeshes - if you replace a submesh, let's say for the torso, you will have to completely change the skinning parameters to adapt to the new topology of the mesh (different number of vertices). Perhaps that is possible too, but I am not aware of an API to do so easily. The system of adding and removing submeshes seems to be intended more for attaching e.g. armor or weapons/tools to the guys, not for implementing LOD levels.
