marmoset AO white edge lines

Simon_____

so i just baked my textures out for substance and everyone was great as usual, except for one the AO map, for some reason i dont know there is white lines on my AO from the mesh edges, the smoothing groups are fine as all the other bakes worked great, ive never seen this issue on an AO before

What was the padding set to for this bake?

the padding is set to 8.0

What does the AO map itself look like, and what does the AO map look like when applied in Toolbag?

New Marmoset user here. Having this exact problem, too. The padding colors for my AO and normal are just completely wrong at seams. I previously baked in Substance Painter (bottom pic, flipped green ch) which had great padding.

If you're using PNG try switching to PSD. There's a bug in 304 with saving padding information into the alpha channel.

Malachite

Thanks, that's better. Looks good in Substance, too.

Any ETA on the fix?

EarthQuake

It will be fixed in 3.05, we don't have an ETA but we're working on getting a beta ready here. Keep an eye on the user group if you're interested.

Was this issue ever actually fixed? I'm getting these white seams only in the AO map. The seam edges are hard, and the islands properly split.

Confirmed that this is a padding issue, but also the baker not handling some UV islands well such that it needs to go into padding. Any idea when this 5 year old bug will be fixed?
