Glad that u found the way... Im not familiar so much on 3d OBJ... I do think vertex color is not the best color export for a 3d model. I will work on export OBJ + MTL
You're welcome ! Also about the 3D export, the mesh looks a like a voxel export with a lot of triangles. When you have time it will be great to add some polygone optimisation during the export. The actual models are un necessary heavy on polycount.
