I have a mesh in “blender” to group materials and export “obj” files, and the mesh will be divided into several in “Babylon”. I’ve chosen the texture group for the export option, but it doesn’t work. Exporting “Babylon” files is not divided into multiple files, but I need to use the obj file.
I’m sorry but I’m not sure to get what the problem is 
Can you rephrase the question maybe?
Thank you. I will post a new post
