I am not sure if it's a problem with exporting from Zbrush, importing into Substance Painter, but when I bake the object, either in Zbrush or Substance, there are visible seems on parts of the model. How can I get rid of those seems?

I'll suggest to use multi map exporter in zbrush, setting normal map to tangent, smoothuv, sNormals and FlipG i think zbrush by default use opengl type of reading G channel, so it's inverted by default if you are planning to work on a directx based substance project, simmilar errors happened to me in maya, so i had to flip g &/or r channel to make the seams smooth in viewport, by the way those hard seams starts to dissapear when applying all the textures you need.

I have tried baking in Zbrush as well, flipping the G channel, with and without smooth uv or smooth normals. It didn't work. Out of habbit, I only work with OpenGL inside Substance.

 

Zbrush export settings-

And for good measure, the displacement map that I also baked in Zbrush (It shows the seems in Blender, but not as much as the normal map)-

in substance if you baked the heigh/displacement channel turn it off to check if seams are still visible, then if they are not, send a screenshot of zbrush displacement settings you are exporting, i can't remember right now the correct values depending on the file type.

I am not sure what you mean exactly, how do I bake height/displacement inside Substance? I can an option to bake the normal, but not height.

I explained myself wrong, i was thinking about heigh channel, and writing about baking, but if there is no heigh channel in use it's ok. I think it's just related to smoothing normals, you may ask in substance discord, there is adobe staff answering questions https://t.co/TwNbSy9D04?amp=1
