Specular fireflies on spec only

Hi all

Rendering on the GPU, we are getting some fireflies, but only on the specular channel (please see attached).

Generally the GPU render appears to have a harsher noise/pixel contrast compared to the cpu. I’m using the default filter types etc. but wonder if this is the best for GPU rendering?

Cheers


Would it be possible to send an example scene to support@chaosgroup.com

Cool, just emailed to Support.

Cheers

The scene is in the developers hands for investigation. Could you please let us know the V-Ray version that you are working with? I tried to reproduce the result you showed in the mage but the speckles where a lot less in my render. Also the GPU rendered generate less noise for the same render time compared to the CPU.
