This happens when I change object’s resolution. It was happening on another object, then I changed it’s resolution than it fixed, but messed up with this ones below. I’m sure the UV is correct and there are no polygons touching the bounds or overlapping, because it worked fine on Unity 4.6 and sometimes it works on Unity 5 as well, depending on the object resolution.
Is there a workaround for this?
It’s directional lightmaps, but this spots show on intensity and directional lightmap.
