I can’t seem to get VRayDirt to work in the Bump channel. It crashes Max when used as a Displacement map since it is geometry dependent, but it shouldn’t have a problem to act as a bump map. Any idea for how to make it work?

You could try the color2bump shader, though I’m not sure if it will work: Chaos: Industry-leading design and visualization software Best regards, Vlado

Unfortunately it doesn’t. I’m creating a generic procedural scrapes map and I wanted to use it as a bump map, but it seems that it’s not possible. Is this something that can be added? Or is it like the combination of VRayDirt and Displacement that makes it technically not possible?

If you want to use it specifically for displacement, it won’t work - VRayDirt needs the scene geometry to trace rays through it, but on the other hand, generating the displaced geometry needs the VRayDirt texture to be calculated… so it’s the chicken and the egg :slight_smile: The VRayDistanceTex te…

I’ll use it for both. Basically, I’ll want to use it the same way I use any other procedural map (noise, cellular etc…). So I might use it as a mix map, or I might use the actual dirt map to create superficial cavities.

Hi, any chance you found out why VrayDirt doesn’t work with bump? Could be a real lifesaver when working with procedural materials. [image] Alpha/Transparency in RectLights? If you want to use it specifically for displacement, it won’t work - VRayDirt needs the scene geometry to trace rays thr…

I think this was solved in the latest service pack… Best regards, Vlado

Great! Looks like I’ve forgot to update :slight_smile: Thanks

Hmm, updated to latest version of vray (2.40.03) and still not working. Here’s the vraydirt in Diffuse slot: And here the same map in Bump (strength at 100): As you can see - not working at all. I tried using it as a mix mask, but it doesn’t work either. [image] Composite vs VRayCompTex I thi…

Which again brings up the question, once VRayDirt (with inverted normals) works in the bump slot, would it create round corners too? Or could it be set to do that?
