Hello, I've been trying to work out my normal map problems for about 5 days now. I am getting seams where the uv seams are from viewing with just the (tangent space) normal map applied in marmoset 2. My UVs were unwrapped in Maya. They are mirrored correctly as well (I've tried a version without mirrored UVs as well). There have been many things I have tried. I have baked the normal from different programs: Maya, Zbrush, and Xnormal. Using a cage as well as trying without a cage in Maya and XNormal. All results still showed seams. I also made sure to bake the final complete model when I baked every time (didn't try to bake half of normal and mirror it). I've also made sure that my vertices were all welded together on the model. The model has also been softened in Maya before baking. Tried padding (dilating) the normal maps. I've went into Photoshop and tried to blur out the edges as well with the neutral blue normal map color (tried combining that with padded version as well (always made sure to normalize when done)). I've been using .tga files (I've tried 32b, 24b, and 16b (with and without the alpha channel). Attempted flipping the Y in Marmoset too. The seams are still there.

Any information towards this would be greatly appreciated. Thank you for your time!

I've also gotten some seams where the edges of some of my polygons are.

The first thing to try is setting your tangent space in Marmoset to XNormal.

I tried it out, I didn't notice any differences in my situation. I wasn't aware that you could do that in marmoset until now, very interesting. Thanks!

Try using fbx, or obj if already using fbx.

Just to double check what you're saying about "mirrored correctly", have you offset the mirrored UV's by 1?
