Hello All,
I have the same kind of pb. I have made lots of tests without finding the isue.
I use C4d R20 + Corona9 hotfix1. on windows. DELL 7810 with 2xXEON E5-2695v3 and 128GB RAM.
There s two similar Big Scenes i m working on. ( about 3.8Gb with a lot of Chaos Scatter). The two scenes are very similar with the same render settings/ cam / Light ( Coronasun+sky ).One works fine but for the other here s what happens:
If i start c4d, open the scene and click render ( local), the render lasts pprox 90 mn.
If Click render again times flies around 6hours , and i do it again again it goes to somthing 20 , 30 hours with a very low ray/s.
If I close c4d and relaunch c4d, re open the scene It s 90min again.
I dont see real differences between the 2 scenes.
Not that the parsing time, Geometry , UHD precomp are normal ( few minutes ) each time.
If you have an idea i m very interested :)
