Yeah, i know that, but what do we/you need them for? It's the texture itself. Without it, you won't see anything. Like if you have made a concrete wall texture, you will see the concrete texture. It's simple. VMT = Valve Material Texture. That defines what properties it has. Is it concrete, does it glow, what bumbmap does it have, folder specification. Simply, you need them both. Yes i understood that. Its a material file, but what do we need them for? make walls covered in admin crosswords? (omg i just realized how awesome that must've been) That's the VTF. Like this: This is a wooden floor texture. You just make it a .tga *saves quality* and convert it to a .vtf. If you want to have something like that on it, you simply draw it on it: It's that simple. You can just do that in Gimp, photoshop ect. You have to do this in the VTF. With the VMT, however, is something different. The VMT produces the effects that come off it. Say, you make it "feel", and "act" like wood, you make a wooden command in the VMT. Or you want it to glow, then you add $selfillum. Or if you want it to blend ect. The VMT is actually the rest. The texture itself is always the VTF. I dont think you get what I'm asking... What are we supposed to do with the admin vmt & vtf files? Why post them? What interests do mappers have in the admin crossword vmt & vtf files? (My original question was actually if only mappers need them, or if its anything we can do with them aswell as make maps)
