Hey Guys,

Ive got some bump maps in the standard bump slots but wanted to know is it "incorrect" to use the global bump at the same time?

Thanks

You can use them all at the same time.

Thanks Tom! Exactly what I wanted to hear!

If a bump map is copied to 2 layers, and one of the layers is additive, is the bump value treated as additive too?

and if you got one in the global bump and one on the bsdf, do they add, or which one is used then?

What's being blended additively is the resulting look of the layer, not its parameters. In this case, no.

In this case, yes they will be added.
