How to have more than one transparency map?

nick2196 · 22 Apr 2012, 17:13

Hello all. I am trying to create a material that has more than one transparency. I am working on a painted material that would have a crackled finish, along with dings and dents, and wear on the corners.

Currently I have one diffuse layer, which holds the color information of the material, as well as "dirt".

I have another diffuse layer which has a "dings and dents" texture, and is applied as a transparency. This works perfectly.

The next step in this material is the crackled finish. I have created another diffuse layer, and imported the bitmap using the same method as the "dings and dents" layer. However, I cannot get the crackle to show up on the material.

Any ideas?

hard to control since it will only follow the diffuse layer on the very top. you can actualy wotk thios time using the UV remember that vray unit is in inches. thom thom has tutorial on displacment and unit.. and have an explanation on it check that one out.

What I do - is to apply a white TexAColor map for the transparency in the diffuse layer. That way the texture is visible in SketchUp and I can UV map the surface, but won't render in V-Ray. Then I add additional diffuse layer underneath which will be visible.
I used the method in these renders: http://forums.sketchucation.com/viewtopic.php?f=333&t=44822
I used it for stuff like the road with the water puddles and the chrome fender with rusty spots.
