I have some very demanding highres renders, with
lots of transparent acrylic boxes with reflective thingys inside, seen through
each other, render settings reflection 4 and refraction 16 (to look through all
the boxes). Sometimes it renders fine - then if i move the camera, memory usage
goes through the roof and rendering swaps for ages. I can see how moving the
camera means reflections see more geometry than in a render that works, so I
have tinkered with MR memory limits to find a way to render these shots. Problem
is, even though I specify a MR memory limit at, say 1024 MB, I see rendering
requires maybe 1,9 GB or sometimes more, obviously swapping and crawling like at
snails pace. I have optimized BSP and divided the image into smaller chunks, but
still I get this heavy memory usage. I was hoping to find a way to perhaps get a
slow render, but one that eventually finishes.
Question is if there is a ressource somewhere
explaining MR memory limits better that the XSI one: "this button does like so."
style - or if someone has tips they want to share.
Thanks!
