Hi, I've been trying out substances new plugin for unity 2018.1 with livelink and I've been having a small issue with the textures to a modular apartment hall set I've been working on where these seams would appear between the pieces as you can see below.
I was using a plane mesh for the atlas and mapped the uvs for the modular parts to match an ID map I made on the atlas, and then I added the textures masking to the ID map.
Now I've attributed the seams being caused by the way substance painter
has been generating the normals with these strange artifacts on some of
the edges that are either 1 or 2 pixels wide, so I tried compensating
that by shrinking the uvs for the parts by those pixels in hopes that it
would resolve it.
But it only seemed to have resolved those seams when the camera is close to the texture.
Is there a better method I should be using to create a texture atlas with substance painter?
I even tried patching those normal edges in photoshop but with no avail, at this point I'm not even sure if it's a problem in Painter or Unity.
