Hello . just want to ask if you ever bumped into this problem ? I have multiple levels. main level for house and 4 levels for grass and foliage . I also have level which contains all the lights ( directional, sky, spot, rec ) . on my main level I have a movable objects ( doors ) I set this to movable because I want it to be interactable within click . I also set detail cell in world settings to 2 so that the appearance of the movable objects looks like a static object right after bake . the problem is after I baked all of the levels one by one and streaming them together, the movable objects ( even the third person mesh which is obviously movable) turned back to its bright appearance . please refer to the image below .
have a wonderful day
