    Hi all especially Unity devs

    In our project we occurred one, I can say big problem and that is loading times in standalone build. We manage find out that this issue is caused by GI data in build. We have indoor game so we use precomputed GI.
    Problem is that in final build GI data for one level have reasonable size, but count of file is insane large, I talking about 2000+ files.... With low setting and indirect resolution per texel is 2 and level is loading around one minute, and 75% of that time game is loading GI data for level from normal HDD, with SSD is not problem, on SSD is loading time around 7 seconds.
    So mine question is, there is a way to make loading faster by reducing or some how pack GI data to one package and load it faster, because I was shocked that some body come with this system for GI that game must load lot of small files instead one big file. I am not programmer, but from mine point of view is very non efficient to loading
    thousand of files for one level every time game is running.

    Thanks for answer.
