[Enlighten] Stuck at clustering jobs when baking lightmaps

Progressive Lightmapper

-

-e: attached project never finishes baking

-repro:
--open attached project (it is https://www.assetstore.unity3d.com/en/#!/content/9473)
--open the "scene" in the JunglePack
--open lighting window
--start the backing
--NOTICE it gets stuck at "5/11 clustering"
---it was running two JobProcesses at max for over 1h and logged nothing into the the editor log
--cancel bake
--change color space to linear in player settings
--start baking process
--NOTICE it gets now stuck at "7/11 Light Transport"

--would be really nice to have some extra indication as to whether it is actually still doing something and not just spinning

  1. Resolution Note (2021.2.X):

    We won't be fixing Enlighten-related issues as it has been deprecated. Please consider using Progressive CPU or GPU Lightmappers instead.

    I had same problem. It happens when there is a big single mesh (not in terms of polygon count, but real world size of mesh ) in the scene. I split the big mesh, then problem solved...

    I'm stuck at 11/15, killed the Unity editor since it was bogging down my whole computer. When I rebooted and re-opened my project the job just restarted. Is there a way to kill the job and recover my project?

    I had the same problem with 5.0.1 and unchecked compressed under baked GI and finally it works!

    I dont know if this heps but in my case I could get around this problem by changing the Indirect Resolution in Baked GI. Before I was at 2 texels per unit and Unity was stuck at clustering. However when I changed that value to 1 it worked like kind of magic. The baking was strange since the scene was darker than expected, but it worked finally.

    Yup - same thing.

    All my lighting is messed up, I can barely work on my game like this.

    Any solutions?

    Update: I waited a few minutes and resumed the processes. CPU usage dropped to 35-75% and the jobs finished in a couple minutes.

    Happening for me with the Stealth tutorial project on Unity 5.0.0f4. When I add the environment asset, it starts running the jobs and hangs. I thought it was my computer and made that my excuse for upgrading. Now I am running 8 4.0 GHz cores, 16 GB memory, and a Radeon R9 270X... but same problem. It seems to hang at "5/11 clustering" for a few minutes at about 70% of my CPU, then at "7/11 Light Transport", and then on "7/15 Bake Direct" it pulls 100% of my CPU and doesn't seem to make any progress. I eventually suspended the processes.

    I have the same issue. I have a pretty big scene with many low tri (50-300) static objects. Had no issue baking lightmaps before, then suddenly just stopped working.
