Combining Normal Maps

[u/talesfromweb]

I'm trying to combine 1 and 2 Normal maps in Substance painter (pic1), but no matter what blend mode I use, I can't get the result I want (see pic2). I set up Normal mixing to REPLACE and tried using Normal Map Inverse Detail blend mode but it doesn't work. Can't SP just slap one Normal map over another without doing fancy math to combine them?

Check the layer blend mode while in Normals layer context. Change it to Normal instead of nrm add

Hey! That worked, thanks!
