Bug (Case 1205918) Physically Based Sky - Upgrade to 2019.3.0f3 causes extreme memory usage

Hi there,

Looks like another issue with PBS, this time if I have it on, memory keeps being used up until it runs out. Current highest count is 30GB. This does _not_ happen if PBS is turned off.

Any help would be appreciated

Thanks

For me, this happens if I constantly update the sky. Such as constantly rotating the sun/directional light or add a script to rotate the light a runtime. So currently it's impossible to do a day-night cycle with the sun rotating.

I think maybe it's because the sky is constantly rebaking and it might not clear until you finish rotating the light so it just keeps filing the memory. I might be wrong though as this is just a guess

 

For me it happens even if I turn off sky rotation

 

Actually if i use normal hdri sky, i have the same issue (it stops growing if i stop the rotation), 23 references if the memory snapshot can be trusted. Such a confusing panel

 

It is still not fixed. I have already sent 2 repro's with timestamps how the memory was rising. I have absolutely empty scene and memory usage rises to 2 gigs and goes further, no matter what i do. There are no assets, just one small terrain. I did not get any response since i sent the first repro. Today i'm sending third, for latest unity version since you prioritize bugs on latest versions.
