I do think this should be pointed out somewhere as I have seen people asking for help with what kind of spec machine they should buy to run corona and having 32gb machine recommended by part of your team.
The RAM usages described here are probably expected. Each render element requires some RAM. Denoising requires extra render elements, which are not visible to the user. Adaptivity also requires additional RAM (that's why RAM/CPU usage may be changed every 5 passes).
That's interesting... so you could add a check box to render but hide Lightselect RE or not ? Maybe I didnt see how to do that already..?Using PSDManager, I'm removing those RE everytime from it...
