Hello. I just tested it, and I couldn’t get material AO to show up in a level with or without static lighting disabled if lumen was enabled. I had moveable skylights and still nothing. May I ask why you state that it does still function as it did in ue4?
Edit: Also, to anyone else reading who may have some insight, I came across this thread in search of information for my current situation. Dealing with massive project bloat, I need to go ahead and do a major optimization pass on my textures. Most of my assets include AO maps and I don’t know if I should keep them, or scrap them if I’m planning on using lumen in UE5. @PrizmIzm You seem to have a good handle on texture packing. If you were making a large open world game with lots and lots of assets, with most textures being 1k or lower for the sake of storage more than performance, what packing set up do you think would be optimal for ue5 and lumen?
