Vray : Combining normal maps in one material

Dustinmaertz

Hello Tech friends. I have a quick Vray material question that I was hoping to get some help with. Ultimately I want to combine 2 or more normal maps with in one material so I can have a sort of detail normal map layered on top of my normal map that holds all of the surface detail. I am using Vray 2.0 Not sure if this is possible. Most of my experience is unreal materials.

Thanks in advance!

You can try Vray Bump material. Create multiple Vray Bump, one for each map, and connect one into the other.

Not sure if it's possible, but maybe a blend like option as well if VRay has it? I know it's possible in Mental Ray.

You could try it the same way like in Photoshop. Put a color adjutment on the blue channel of the secondary Normalmap and reduce the output range from 0-255 to 0-127. You can simply overlay it now without affecting the base blue value of the underlaying normalmap.

I hope this works, need a cup of coffee first to start my brain.

Thanks for the input and ideas everyone! Direwolf's suggestion of using a normal bump for the base and adding additional normal bumps to the additional bump slot was just what I was trying to do. Now I can change the tiling of each normal map on the fly. Thanks again everyone.
