Need Help with weird visible polygon issue

[johns58923178]

  I've got a barrel I made and have this issue where each polygon side of the cylinder show visibly in the iray renderer.  It's a smoothed object, I cant find anything wrong with the geometry or the unwrap, as well as no issues with the normal bake or any textures. Yet when I position the lighting in certain angles it clearly shows all the individual polygons and looks terrible.  I wasnt sure if this was a problem with the renderer in substance painter or what.  I did 6 assets before this with the exact same pipeline and they all worked great.  For some reason this simple barrel has given me a lot of trouble. 

Not sure if this is related, but I exported all of my other asset's normals using the "Document channels+Normal+AO" output template, yet with this barrel thats giving me trouble the normals looked horrible with that same output settings (with DirectX Normal map), the only way for me to get the normal map on this model to look good after exporting and applying it to the mesh was to export the textures using "PBR Metallic Roughness" output template.  Which seemed weird to me since I'm using the same scene with the same settings to render all my models.

Any help would be greatly appreciated.

Hi @johns58923178,

Thanks for the message.

I remember seeing a similar issue, and I think this was related to Ray Tracing rather than Substance Painter directly, so nothing wrong with the Normal map. In which software the textures will end up being? Does the issue appear in this software?

Let me know.
