    Hello,

    I was running out of disk space -- my laptop unfortunately has a non-upgradeable 256gb drive, so I'm usually bumping up against it's limits. But I shouldn't have been.

    Turns out my Unity 5 test project, which is just one small scene with maybe 15 objects, was taking 16GB of space. Almost all of that was in the enlighten folders.

    I deleted them so I could keep working on non-test stuff, and now that I have Unity 5 open again, enlighten is doing it's thing and eating up disk space slowly but consistently.

    Is there a way to limit how much space it uses?

    Hi! We keep files in the GI cache to reduce recomputation when you make small changes to your scene or open one that has been computed in the past.
    You can set the GI file cache to get automatically trimmed. Go to Preferences -> GI Cache -> Auto Trim and set a lower size. Default is 25 gigabytes so your project is still below the default trimming threshold.
    Files that are in use for the current GI computation will _not_ get removed. Setting the cache size way too low can cause a lot of recomputation when you make changes, so there is no good default value... It will depend on your scene and project size.

    A later Beta will have a shared GI cache instead of one per project, that should help when you work with many different projects.
