Hello, I had some problems with fireflies and was able to solve the issue by lowering the GI clamp value from its default 100000 to 1.

I was inspired by this tread:

viewtopic.php?f=9&t=44127

I think this might be interesting for other users doing architectural visualisations where caustics most of the time are not so important whether fireflies can sometimes be a pain...

Thanks Andreas. The recommended (by Otoy) starting value or GI Clamp is given in the Octane Notes link in my signature.
