Normal Maps are SO broken in my HDRP/Lit. Please Advise!

Unity Engine

I have tried many different ways to generate the normal maps. I read a bunch of blog posts explaining exactly how to set up Substance Painter etc… I’m still getting this bizzarre issue where the map “Breaks” at the UV seams.

It’s like the normal map only wants to work on one side of the model.

I’m attaching an image to show what my issue is.

The Mesh came from Zbrush,. Textures came from SubstancePainter. This is in Unity 2019.3.15f1 - If that helps.

Thank you in advance for any advice/help

Hi, hard to tell.

HDRP use surface gradient for normal map with HDRP/Lit, but we have never experienced such a problem.
Two thing:

  • are you able to provide the mesh and the normal map so we can reproduce the issue?
  • Try to use the master node Lit shader in the shader graph. This one don’t use the surface gradient framework to see if it solve your issue.

thanks

Thank you! I will try the Master node and let you know.
I’m attaching a rar with both pants objects and normals if you are willing to take a look. -Thank you for that!

Thanks

You forgot to change the normal texture import type to “Normal map” :
