/3/ - 3DCG

Not really much to share, last hour or so I've been trying to find the root of this issue I have just been using a simple sphere made in Houdini, quick-UV'd with the new game auto UV tool (but any other method has the same result). Just make a sphere, UV it however you want (leave an exposed seam so it's easier to see), export to Substance, and apply any material (or even worse, a smart material). As you can see on the image, the seam is there, in this case I simply applied pure copper to it.

I've tried tri-planar projection, doesn't work (it does help pattern-heavy materials ignore the seam so you can't see it very well as they kinda hide it, but it's still there). I've tried with baked maps and with no maps, same result (so it's not a normal or curvature map bake issue). Isn't the whole point of applications like Painter that since you are painting on a 3D mesh, it doesn't give a fuck about UVs and its seams? Quite sure Mari for example cares nothing for UV seams.
