Hai, i'm having a bit of trouble getting some skins to work. I've named them metal_box_skin002 and metal_box_skin003, they have VTF and VMT files, but i can't get the skins to work. Same with the button_skin001. Anyone know how to fix this? And do i need to edit the actual model?

Unfortunately, yes, you would need to recompile the model in order to use the extra skins. You can't just drop in a new material arbitrarily and have the model know to use them. I want to say there is a pretty simple tutorial of it over at Interlopers.net, but it's really early and I'm not totally positive.

Bugger, i was afraid of that xD I can't find anything on Interlopers, so I'll grab kHED and see what I can do. Thanks

You can also check halfwit-2.com, they might have something. If not then check the Valve Developer Wiki, they will probably have some good stuff but it might not be as easy to digest.

Okies, i've figured it out. I had to edit the QC file it spits out to ask for skin families rather than one texture.
