First, what does the material name field determine? if i name a gravel shader tough_terrain_gravel, will it produce dust from grenade explosions and a gravel sound?



Second, How are the yellow sandy paths blended so smoothly with the green grass in the pathways on bloodgulch? is there a shader that will take multiple diffuse maps and blend them? I am looking at the template folder and i cant seem to find this. I have found shaders that can read multiple specualr and detail maps and blend them, but i have no clue how it works. Ive tried writing my own but i cant see the difference. quick shader tut anyone?
