Normal Map Problem

Priss

Hello! I textured this asset with substance painter and when it is rendered there it doesn't show any problems with the normal map, but when I try to render it with marmoset it shows some strange artifacts. I tried exporting the maps in different formats but the problem was not fixed. 

This is a screenshot from substance painter


This one is from marmoset:

Any help would be greatly appreciated  

Thanks!

Priss, try changing the tangent space of your object, from whatever it is now, to any one of the others, then back to marmoset. Here:

  

Sometimes that fixes these kinds of errors.

Scruples

turn off shadows and ambient occlusion to check if it's that, adjust bias appropriately to fix.

This looks like a bit depth problem.  It occurs when the topology difference between your HP and LP is so fine that an 8 bit range can't store the appropriate values.

tl;dr to remove normal banding, bake as a 16 bit per channel TIFF or EXR format, and convert to TGA.

 Exporting the maps from substance painter as a 16bit TIFF got rid of the shading error. Thanks man!
