Title: Flickering Animation caused by rough metal
Post by: Dezorian on 2017-02-25, 16:59:22

Hi,
im working on an animation of a bath szene. In this Szene are some rough metall parts like aluminium or brushed steel. The parts cause alot of flickering when animated. Everything else has no flickering what so ever and looks clean when rendered.
Im rendering with 30 passes and full denoise activated.
Is there a way to get rif of the flickering on rough metal materials?

thanks in advance

30 passes aren't enough.
And, I suggest to use Noise Level >4% and to avoid Passes limit.

An example of this flickering would greatly help find a solution. If that's something you cannot share publicly, you can contact us about it at support@corona-renderer.com.
One possible solution might be increasing GIvsAA parameter. That would put more rendering power into glossy reflections at the cost of antialiasing (you would get nicer reflections in lower amount of passes). But that's just a guess, so I might be as well wrong.
