Hi,
I just bought Octane, testing it on my Macbook Pro retina. It looks promizing and I can't wait the Cinema4D plugin to be released for mac.

Well, i ran my first test today, and i've got an issue that i want to discuss here : do you know how to avoid the stranges pixels artefacts you can see in the red circles ?

thanks in advance for your help.

Well, i tried a daylight animation, but the artefacts are still there...

Must I lower the hot pixel removal value, or raise it?

If you're talking about the red/bright spots on the sun, on your video then:
You need to increase the saturate_to_white.

I'll try that one, thanks !

I made a second test...

In this case, i was figuring how to adjust contrast, but i'm very happy with the result, considering I stopped the render at 6mn (GTX 650M)

Any clue about this one?

Ya, PMC should clear that up a lot.
Also, try raising the caustics blur setting in your kernel settings. This might not help in this case, but sometimes it does.
The hot spot remover slider under image settings will zap some of them out, but it will begin to blur the image if you lower it too much.
Last, increase the size of your image. Those white dots are 1 pixel each, so if you have more pixels, those dots will be much much smaller.
