Multiple textures on top of each other?
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!

The Source model formats (and most other) only support a single material assignment per face. Layered textures are usually handled on the shader level, so unless you are in a situation where you can write custom shaders, your best bet is to look for material attributes that let you blend textures togther (like $detail, although that is limited to one additonal texture).

Otherwise the common solution is to apply different materials to different parts of the model, and use $texturegroup to create combinations for each skin.

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