Title: Long computing secondary Gi times
Post by: PMVis on 2019-01-09, 11:52:32

I have been having an issue since installing corona 3 with long calculation times for computing secondary gi. I switched in the middle of a project from corona 2 to 3, the scene was rendering fine in 2(like 30 secs to calculate secondary Gi) but now it often estimates over an hour.

-This problem is not scene dependent as it has occurred on two scenes now. These scenes have a number of high-res textures(8k) but I know its not a RAM problem as I am using only half of my RAM(64GB) on each scene.
-If I restart my computer and start a render it calculates in seconds. If I work on the scene and try to re-render then the issue occurs.
-If override the scene with a clay material also no problem.
-The problem seems to mainly occur at rendering higher resolutions like 3500-6000.

I have the newest NVIDIA drives installed for my machine.

Here is my machine specs:
Intel Core i7-5820K, 6x 3.30GHz, NVIDIA GeForce GTX 980 Ti 6GB , 64G RAM, Windows 8.1

I would appreciate any help, as I am not sure where to get started on fixing this issue. Cheers.
Phil
