Arnold specular flickering


#1

Hi!

Im doing some animations with Arnold, ( im new to it ) but i keep getting a weird specular flicker that seems to happen only on the bevels, it also happened on some cilinders that where simulating wires. ive tried upping the specular in render globals but doesnt seem to do much, also tried with the arnols standard shader and with a blinn. cant get the flicker to go, could it be the geometry?

Here are some examples of what im talking about:

Thanks in advance!

only thing that occurs to me ( I only have a little experience with arnold ) is that your renders look too sharp for animation, fixing that might help. I’d use gaussian reconstruction filter and never mitchell of lanczos - they’re ok for stills but they create edge artifacts.

Are your models faceted? If they don’t have rounded edges, that could cause this
