Recurring error while baking scene in Unity 5.0.0f2

Hi,

While Unity is baking the GI and Light maps, I often get (about every 2 or 3 bake) error like this in my console:

1. kSuccess == m_Result
2. Failed opening GI file: '62/62b0421e623e23067c8aa88df6415c44.rsc.sse'.
3. Integrate failed on Light Transport job.

Those errors show in a loop and the console shows 999+ errors.

This is done in a very simple scene with a plane, a cube and the default light + skybox + camera.

Is there anyone having this issue ?

I can give additional infos upon request.

Thanks !

 

Done, ticket number is 674683.

 

I encountered the problem in 5.0.0 RC3.
The scene baked OK till yesterday. I had a computer shutdown.
Now nothing helps - clearing baked data nor purging GI cache through Unity menus.

Clustering went well but after that it failed on light transport phase.
Plus, look at the memory usage

edit: The errors stopped showing when I copied all things from Hierarchy to a new clean scene.

 

Since my update to RC3, the problem hasn't occured. I'll report back if it happens again.
