PBR Export Issue

Noanoww · May 2 2026

Hi everyone, does anyone here know why this could happen? When I texturing in Substance Painter everything is fine, but when I export PBR to Blender, why does this happen?

The seam is ruining the shading.

But in substance everything is fine.

This is the Substance Painter setting when I want to export to Blender.

Hi! I would make sure the normal map is OpenGl and the texture sampler in Blender is set to non-color. If the normal map is DirectX, you could also flip the y-channel in the shader in Blender.

Hello, I have done everything you mentioned, but it didn't work.

this is either
a colorspace issue - make sure you're outputting raw from painter and importing linear to blender (i don't know what blender calls it)
a tangent basis issue - make sure your model has the same tangent data and triangulation for both the bake and the render meshes. if you're using fbx there's a tickybox for exporting tangents with the model (assuming blender's fbx exporter isn't complete ass)

To allow for your issue to be reproduced, ideally share files.

You should use Weighted Normal modifier before you export it to Substance. That's your issue (in case you still have it in OpenGl channel)
