All the three UV-maps are on top of each other in C4D. On import only ONE material is "available". One layer only showing in BP UV Edit.
Doing a small area lasso selection of polygons in the UV-window shows up as selection in several places of the mesh in the object window. This indicates that there is an overlap of three separate UV-meshes.
How do I get the three UV-meshes separated to allow for each of the three jpeg textures? At import time - or after import?
The object w/the three textures shows up fine imported (obj) into MeshMixer.
