The .VMT has to have the exact same name as your random material from Blender for the game to register it, and from there as long as your .VMT specifies via the "$BaseTexture" and "Bumpmap" commands the filenames it should use for textures then you should be all set.

Yeah, I'd been looking for a solution for days. Turns out it was as simple as clicking a button.
But now this thread exists, so that anyone else doesn't have to struggle like we did!

I've solved the problem.
It turns out you need to assign all new vertices to the material in blender (with the name of the texture file)

Some parts of my model still ignores my texture / usues vanilla texure.

I'll make sure to download the newest version, thank you. Carry on with the good work!

I have been using this wonderful tool for a week now, but I can't get it working correctly.
I've made a simple cube (in blender) and exported + compiled it. The model/collision mesh works fine in-game (HL2). However the textures do not, at this point it's highly unlikely that it's an issue with my VMT files, I've tried all variations I can think of. I always tweak the UVs in blender.
> I recently imported my simple replacement model for the pistol, based on the original one from the game - it works, even parts of the textures. Still, the texture is distorted, and some part doesn't even have the same color as my test texture, so I figure this is an issue with the UV map of my models.
How do I export the model with my custom UV correctly from blender?
