(disclaimer: I’ve searched already… I’m not a good searcher)

What is the proper way to set up a Vraymtl to use a normal map?

Thanks!!!

The way I do it:

- Apply a 3ds Max normal map in the bump map channel  
- Assign the normal map bitmap in the normal channel  
- One Important thing: if you are working in LWF you have to take into account that the normal map must not be gamma corrected so, depending on your workflow, you may need to compensate the gamma with a color correct, or overriding the gamma settings when you load the bitmap.

It works for me 🙂
