Hi everyone. Is there any way to force normal maps work. I tried gamma, I tried green channel inverted, nothing helped. Here is an example of the test scene where I baked normal map and it works perfect for scanline render and does not for Octane

Hi be_fast,
I'm doing some tests, could you tell me which software you used to generate the normal texture you're using? Was it created using the 3dsMax tool?

Did you bake the normal using the octane camera in bake mode? I could never get a good normal map bake from octane in 3dsmax...

I looked at your file, not sure what the issue is, the material in octane is glossy and the one in scanline is not?

Hi, thank you for reply
I have used 3ds max 2020 scanline to bake normals map with projection modifier on lowpoly model catching highpoly

The issue is octane doesn`t render normal map correctly not as a glossy material and also diffuse material renders incorrectly with normals as well. At the same time scanline renders this normal map perfectly. You can see that at the images I have attached above

Hi be_fast,
I'm not sure I fully understand the issue. Have you tried checking the invert box on the normal map?

Yes I did. It looks fine on your render.
I have artifacts somehow

Hi be_fast,
try this:
In material editor create a 3dsmax standard material
Add the normal map then apply the material to the object
In Render setup/Tools/Material Converter, use Convert Current Slot Material to convert only this material.
Now, you can see that the standard Normal Bump map is incorrectly connected to the Bump slot instead of the Normal slot
Swap the map from the Bump slot to the Normal slot
Here is the result attached.
