I was rendering a scene which is not quite large in 2k size, and it always shutdown because of out-of-memory issue(my computer has 128GB MEM).
I checked a frame which rendered and completed in 1k, the render log shows it took 90GB and half was noted 'unaccounted'. And I checked ray counts, it seems 50 times of my regular render's ray counts.
So I wander if the large amount of rays cause the heavy usage of memory? And I also want to find out how to reduce the rays(memory usage)..
Thank you.... waiting to your answering
