Thank you for the answer, Rectus. I'll try using the $detail parameter.

To put it in short, i have 5 materials attached to my model in Blender and i want all of them to act as if each of them were assigned to all faces of the model.

I have been trying to figure out a way to optimize my workflow by using layered textures. Instead of having, say, 13 unique VTF files for all 13 skins of my model, i would like to have only 5 textures; first one is the base texture and the other 4 could be layered on top of it at will (managed by $texturegroup parameter).

I would simply use the $color2 parameter for these 4 layered textures to create dozens of skins, saving memory and time, and will also use $alpha parameter to disable/enable some of the textures for specific skins.

So, how do i make my textures to be projected onto entire UV map, instead of only being projected onto assigned faces? I've also seen others struggle with this. Thanks!
