Well, new developments! So the reason it wasn’t importing correctly is because the 3.4 plugin exports no simulated verts if you leave a percentage of your verts at a cloth weight of 0. We only found this out after we flooded the meshes with a value of 120 (it exported and imported successfully…looked like crap with 120 everywhere, but it worked). We then worked our way backward. I’d suggest simply flooding your mesh with a value of 0.001 before painting for the time being. We’re going to poke Nvidia about this, but it wouldn’t hurt for you to do the same.
