I encountered a problem rendering a chrome surface (see attached image). Each bucket looked a bit different from the others.
I tried a lot of things: set Ray detail region to 360 degree detail, set the ray detail multiplier to 1, tried to render with only one thread (of course four times longer to render

). Nothing really worked.
When I turned off "Stablilize ray detail in motion" in the Render subdivision settings (rendering with
all threads and the other things as I wrote) the render errors seemed to be gone, but render times went from 4 minutes per frame to 7.
This sounds illogical. I thought the stabilize function consumes more render time?! However I don't really know what this special feature does. I'm still rendering a sequence, so I don't know yet how it will look in motion.
