I was unshure to post a question because i saw there are a lot of answer on this topic but I try all and don’t get good result.
I have a product configurator based BP so my product is multiple BP for many assets assembly the product. First i created the product with no level a part the persistence. lately i implement two different level, one with a light interior system and one with exterior light hdri skydome directional light. I switch by the two with a keyboard based flip-flop on level blueprint that change the level. All works but the baking process work well for the exterior light with skydome but i get weird map, like occlusion compenetratio( but this is only apperance) on interior light. I followed the process. First make the light scenario for all and bake one at time, the interior light won’t bake correctly, after i use all at once the same. I in unreal 4.27 hope someone can direct me on the correct way. I get mad about it and shure i search a lot of material online to get an answer that unfortunaely doesn’t work to my scenario.
thanks to everyone
