    Hello Unity, All,

    I was informed that async load of scene lightmaps is already in Unity 2019.2.1. Can anyone please confirm if this true?

    In my VR project I'm loading a lot of small sub scenes additively and seeing performances hitches when scenes with lightmaps are loaded. I was told this should already be fixed, so am trying to find out for sure.

    Thanks @Peter77

    I don't think it's that -- the performance hitches relate to the following quoted feedback:

    "For the large time spent in EnlightenRuntimeManager.UpdateAlbedo, I believe some improvements went into 2019.1 to remove these main thread sync points (shown as large time spent in Gfx.ReadbackImage in the profiler capture) from these functions."

    So it does specifically relate to the lightmaps. Although I do realize that Enlighten will be heading out to pasture soon!

    Not related to this issue specifically - my current project lighting looks better with Enlighten, I get weird artifacts if I try to use progressive, which I'd prefer to use.. but that's a whole other story. :)

    Hey @WildStyle69,

    Improvements that you're referring to landed in 2019.1. Hope they will improve your case!

    Cheers!
