I am working on a large model around (600mb) with SKP19 and Vray Next. Most of the scenes are rendering fine except one scene (vray stuck at building light cache and using almost 100% of the ram and very little of cpu). My computer is equipped with i9-9900k, rtx 2060 with 2666mhz-32gb ram and I cannot believe it is struggling with this file. Other scenes are using about 40-50 % of the ram. Last night I started a batch render before leaving work and after 13-14 hours the scene was stuck at 60-70% at prepass lol and I tried almost everything to optimize the file and still no luck. I tried cutting just the objects in the visible scene to a different file and still no luck tried purging the file about 100 times. Usually my computer works and renders fine with files above 1gb just fine.
