Normal Map baked in Substance Painter shows defects like 'ripples' when applied in Blender

[T4sty]

I baked a Normal Map in Substance Painter that looked perfectly fine until I imported it into Blender.

• I’m using Blender 4.0.1.
• I triangulated the mesh before exporting the model to Substance Painter in FBX.
• In Substance I baked and used OpenGL to export the Normal Map.
• In Blender, the Texture Image node ‘Color Space’ setting is set to Non-Color.

I’d appreciate some help.

Do you have modifiers in the object? some modifiers messes with the UVs.

These are the Active modifiers:

I didn’t actually ‘Apply’ them because they applied automatically when exporting as FBX.

Mirror modifier causes overlapping faces. Try applying that, UV unwrap, Then export and bake.
Or it could also be the weighted normals.
Try applying everything, unwrap and export.

It looks like it’s the weighted normals.

Try deleting the triangulate, or put it above the weighted normals.

It’s probably because weighted normals relies on the topology of the mesh, and by triangulating it you are changing the topology and break the normals that was assigned to the faces.

I just did, but still looks the same.

Do you think it could be a problem with the normals?
This is the model in solid view with all mods applied:

You could try posting the blend file and texture here it would be easier to find out what’s wrong.

Try exporting the normal map in png 16 bits. I tried it and it looks clean on mine.

Thank you!!! Can’t believe it was that simple. Looks perfect.
