Hello Everyone!
Old topic, old issue, getting me crazy.
I am modeling a house in Maya 2017 and I have been baking my textures with Arnold.
Until yesterday, my bakings were perfectly fine until black seams started to show up on my final AO's and/or material bakes.
I haven't changed baking settings but increase the AO a bit to have stronger shadows.
Here is an example of my issue:

A few things I tried:
remap automatic, optmize, turn off renderer 2.0, scale down my UV, change materials, bake the texture, bake AO only and so on.
At last, I renamed Maya 2017 prefs folder to reset maya preferences just in case I accidentaly changed something without noticing, but that cube+cylinder is an AO bake to texture after my preferences were reset.
I don't know where in Arnold 2017 change the fill texture sim of the old mental ray, I don't even know if there is such an option, but the thing is, I have been baking without it anyways and it was working:
See at this fireplace base (cube):

So yes, if someone knows how to fix this, I would love to hear how.
