Hello,

I'm getting black pixels on my render. Does anyone know how to fix this?

Rendering with Redshift, I've tried different lighting and materials. As soon as any reflection is added the black pixels show up.

I've tried messing with the sampling and they are still there.

I'd also love some feedback on the simulation, mostly on the white water. Any tips on how to improve that would be most welcome! I've used a mix of volume and particles, had to set up some elaborate particle deleting. It's still not looking 100% imo

Thanks in advance!

Try increasing the limits. It might be that when you run out of bounces, all that's left is black empty space. Try surrounding your scene with geometry or using and HDRi map.

Those look like NaNs to me.
