Edit: sorry I forgot a crucial point. I am of course using a displacement map too. This question is whether the normal map should go into the BSDF normal map slot or the dispacement normal map slot. When using a displacement map along side, going into the displacement Height map (image in comments0
I’ve seen SO much conflicting information regarding displacement maps and normal maps.
Most people say the normal map must be plugged into the BSDF and not the displacement node.
Here is a test with normal map plugged into the BSDF vs Displacement node (Displacement and bump turned on) You can clearly see the bump is far nicer and sharper with finer details when the normal map is plugged into the displacement node
Here are some more tests. You can see BOTTOM LEFT with the normal map plugged into the displacement node, there is a nice displacement with nice fine detials from normal map.
If I then plug in the normal map to the BSDF instead, the displacement map appears to be less obvious and “flatter” - BOTTOM MIDDLE
I thought maybe the nromal map axis is incorrect so i flipped the green (far right) but that is totally incorrect
I know its not a big issue, if it looks better in the displacement node then that is great. But I just want to get a concrete answer if there is a 100% correct way to do it. Because most people say to put it into the Principled BSDF, which I believe is incorrect from my tests…
