Substance normals rendering black in Maya Arnold

[sdrake.cc]

Hey!

I'm super stuck and am not sure how to troubleshoot this. I've looked a lot on the forum too and have yet to find a solution. Help!

When I try to render my Substance Normal map, Arnold outputs these strange black artifacts on my model. The black spots change placement depending on where I place the camera.

The normals also appear black and strange in my editor view too.

They are setup using the aiStandard shader.
I have my texture files setup correctly: Image file set to raw and color space is tangent space.
I tried removing the alpha channel from the map, which didn't work.
I tried a different normal - not from substance and that was fine on this mesh.

All help much appreciated!

Can you share your shader network (screenshot and scene)? Substance to Arnold guide here.

1. Are you using the standard (deprecated) or the standard_surface shader?
2. Are you using Maya's bump2d (Tangent Space Normals) or the Arnold normal_map shader?

I guess the problem is to have the normal map file texture in sRGB colorspace instead of RAW
