vray blend + vray dirt

[mikeh]

vray blend and vray dirt gives one a sort of blend of the base material and dirt (which is what it is supposed to do) but is there a way to use vray dirt as a multiplier to a base texture such as you would do in Photoshop? The shellac check box in vray blend doesn't seem to accomplish this.

Use a mix map with the vray dirt in the mix amount slot. If you want to blend two materials, use the clean material as your base, your dirty material in the first coat material slot and the vray dirt in the blend amount slot of it.

Jo,
i tried both of those methods and didn't really get a "multiply" effect. What they gave me was a half and half...half dirt and half base texture. What i'm looking for is what you would see if you overlayed the dirt on the texture and set the dirt to "multiply" as in photoshop.

Ah getcha - someone is working on a map that has photoshop blending modes built in - morbid angel had it in one of his threads.

You could use the RGB Multiply map. It will save the trouble of requiring a external plugin. I have also develop a photoshop layer blend map for our company so with could updated with every max update with having to wait for others to update. When i get some time i will finished and may put it here in the forum, but for now he doesn't work in bump/normal map slot and is missing 3 modes. But has a few features not available in the other plugin like layer masks for each layer.
