Multiple Materials Modelling:

[Lonecat Nekophrodite]

My first challenge. Making human bodyarmor model consists of multiple materias. something I've never done before.
What i did before used single material which were easier to work with. Now i want a new unit model for Southeast Asians. This is what i've did now.

Too bad I cannot import and make a proper unit model even if the model itself appears to be 'valid'

What did I do wrong?

Here likely you have empty materials that need deleting. Materials with no faces assigned to them.
