I am seeing these artifacts appear, anyone else seen this and have a solution? Shows up when I am baking my lightmaps with Beast.
It looks like you might have holes in your geometery.
Did you make that room at a scale that was way too big? Cause there are some operations that cause tiny holes in the corners when you scale them.
Of course, I could be wrong.
It is not the model, it only shows up when I bake lightmaps. If I use dynamic lights they do not appear (and were not there in 2.6.1).
potentially you set the texel density to small for the complexity of the geometry and now have lightmaps that get these artifacts due to bleeding from the “empty space”, assuming you have a bright bg color on the lightmaps, not black
