Baked Lighting weird artifacts

schmaled

Hey guys!

We are working on a game using Unity (on version 5.3.3p3 right now).

We are baking GI and Lighting using Directional Specular.
I generate all of our lightmaps in Maya.

We've stumbled across this weird artifact and I'm not sure where it's coming from. It only pops up in a couple locations and is pretty annoying. (see image)


Has anyone encountered this before? Were you able to solve it?

Thanks for any help

Yeah. Look at this thread, a little further down in this forum section:

Realtime GI/Enlighten problem

@Eric ChadwickThanks for the heads up. I'll take a look

Yes, that artifact looks similar to the one I described and illustrated in the topic that Eric linked. Still, I had it with Realtime lightmaps, not Baked ones. 
My bug is confirmed and tracked by Unity here:

You say that you are generating all your lightmaps in Maya but that you also bake them in Unity? 
Can you show wire view of that geometry? 
Have you tried custom 'System Tag' value to put that object into unique atlas to see does it resolves the issue?

With object selected, going to Lighting>Object, you should have a preview on the bottom where you can switch between various modes showing how exactly that object got unwrapped, on which atlas and how it's irradiance map looks like.
