No idea, I'm bored with doing the 7 daily refresh side missions, so I'm flying around picking off the points of interest, weapons and attachments. I've killed Walker, and wiped out the Terminators, is there more after that?
Found how it works. 2 Rules. 1. For models, there should be multi material from at least 2 slots. 2. The texture for the face should be Head.rsb Then it will be normal to take the face texture from the atr file. All other names will automatically work only as a mandatory texture for the model and if it is removed the model will have a white face.
