Using map textures with variants of the Material Tool or E2

[Ibram Gaunt]

Hello. Recently I tried to use some materials that are not listed in the Material Tool's menu. I used an advanced browser to look up textures, much like I'd do to props in a browse menu. The materials that I tried to use are mostly ones that are used for mapping, such as various kinds of concrete, metals, plastics, grass etc. Some of them actually worked, like skyboxes. Appearently, even the image of some achievement icons can be applied to props. However, the vast majority of these materials appear to be incompatible with props, I tried to use Material Tool as well as an Expression 2 chip, but neither could apply them. Is there a way to use these materials without modifying the game? And if not, will Valve throw a tantrum if I make a Gmod addon from some of their map textures?

PS: I'm not sure whether it belongs to Help and Support or not. If it does, please move the thread.

Those are blacklisted by the material tool/E2 because they're global textures and if you recolor them, it will affect every instance of that particular texture on the map. The skybox textures aren't blacklisted, though: if you manage to find the one for the map you're playing on you could potentially recolour it.
