Hi all. I’ve been stuck on this problem for a couple of days now. I brought my issue on both the Allegorithmic (substance painter) subreddit, and their official forums, with not a single response! I’m wondering if the issue is actually with Blender, and how I’m transferring/prepping/saving my meshes – so I’m posting this here now.
Whenever I bring a model into Substance Painter, and bake the low poly with my high poly mesh, I get these horrible seam lines where I had cut the UV. They become incredibly apparent whenever I call on the curvature map to do something, i.e.- create a masked fill. I tried near every combination of bake setting but nothing seems to work. Tried trilinear projections, per vexel, etc. … nothing. When I export my meshes from Blender, I make sure no edges are marked sharp. I export both the high and low poly meshes as fbx. I made a completely new mesh just in case it was a problem with my file, but still had the exact same issue along my UV seams.
Including reference image. I appreciate any and all suggestions. Thanks.!
