Hello Everyone,
I was experimenting with ue4 to get most out of its light bakes. During my tests I noticed weird behavior. My lightmap UV’s change or move during the baking process.
Lighmap UV’s are unwrapped by hand. I made lightmap pixels snap to the corners to avoid light leaking. Somehow they change during light baking and the pixels wont align with the corners anymore.
( Im open for better and easier solutions to avoid light leaking. )
