Hey everyone, I am having a critical issue that is stopping my demo from becoming finished. Background: This is a mobile environment so draw calls are sensitive. Originally, a main scene would asynchronously additive load a single scene " Level_0 ", but unity freezes for a good 5 to 10 seconds in doing so. Although this freezing is extremely undesirable, Level 0 contributes only 2 draws. In attempts to reduce the 10 second freeze, I split Level 0 into 23 scenes. When asynchronously loading 23 scenes in additive mode, Unity freezes 1 second or less; unfortunately, this creates a huge problem of 39 extra draws from 23 new light maps. PROBLEM: Is there a way to consolidate 23 lightmaps into one map?
