Title: specular flickering on reflective object rendering an animation
Post by: leo_surrealismo on 2015-05-20, 21:21:41
hi,
As you can see, there is a light flickering, or fireflyes on the vases and cooktop.... How can I avoid this?

thank you.

You need more AA rays to resolve that fine detail. I would try to decrease GI/AA balance.

But before that...  do you by any chance use rounded corners feature? It often amplifies these problem.

Can you show the material setup of the materials with fireflies? Maybe a workaround would be to change reflection glossiness to something like 0,999.

hi,
this is what I did:
1. lowered gi balance vs aa to 12
2. increased glossines on some materials.
3. increased de pass from 100 to 150

It helped a little bit, but it persists.(see pictures)

I´ve attached 2 material settings.

I can send you the file If you can help me.

thank you.

Oh, it's a blend material. What kind of lights are you using? It would help if you could send the file. You can submit a new support ticket with the file ( https://coronarenderer.freshdesk.com/support/tickets/new ) and we will take a look.
