hi all i know about vraydirt material but not all ..
i have texture (brick) in DIFFUSE slot and bump (brick texture) in BUMP slot - how to use and VRAYDIRT material for this texture???
where to put this material (diffuse and bump slot are busy)
Put the vray dirt in your diffuse and in the dirt you’ll have an ‘unoccluded’ and ‘occuded’ section, with rooms for maps. Stick your brick in both, but in the occluded put it within a colour correct and add contrast/make it darker.
