Mesh Map Baking is Broken

[Kabinet]

I have been trying to texture an extremely simple model in substance painter, but when baking mesh maps, I end up with ugly artefacts on the back of the model, it seems like the normal just doesn't generate there, but there is no geometry in that shape there, just a large quad at the back, and nothing occluding it. I have triple checked my face and vertex normals, UVs, removed any duplicate vertices, deleted and recreated the problematic faces, and just about anything I can think of. This is in a fresh substance painter project with 2048 texture size on everything, all I did is bake mesh maps. (For reference this is a part of a larger model I exported on it's own to isolate the problem)

Thanks in advance for literally any help at all.

Hello @Kabinet,

Thanks for your message.

My first guess would be a collision of the normals between close objects from your model.

Unfortunately, some context is missing to give you a proper help. Could you show me your high poly model ? Or better, send me your low/high model so I can dig deeper (if you don't want to share it on this thread, you can send it directly to me: cdellenbach@adobe.com).

I'm sure we'll get to the bottom of your problem.

Have a nice day,

Thank you for your answer, I managed to fix the problem by thickening the mesh.
