I skimmed your sample (http://www.babylonjs-playground.com/#GTHTR#1) and this was incredibly useful for getting the mesh to clone properly on mobile. Unfortunately, once I use geometry.copy, the subMesh data is lost and I am unable to apply my multi-material. (I have subMeshes on the original, but only subMeshes on the clone) such that the textures are screwed up. On the other hand, if I don't do the geometrycopy, I am unable to have unique animations on the clones. Is there some way of doing geometry copy, but maintaining the subMesh data? Thanks in advance for the help!
