Ocean shader

[Flavius]

Hi there all,

I was wondering if anyone else feels the need for a dedicated OPTIMIZED ocean shader which renders fast. All my works include a big sea/ocean and the render speeds drop to half when I use refraction. And the renders are incredibly slow (noise on ship's decks never cleans properly) so I kind of have to render twice, once with water then only the ship and composite these together. It's quite a nightmare.

Vray has the same issue, renders times are destroyed when turning refraction on .

Thanks,

Do you turn on denoising on your renders? Its helps immensely!

Also, and I'm sure you've tried this but just incase; Playing with the refraction value by lowering or raising in small increments while in interactive view may help you find a sweet spot. Sometimes, even if using real values for glass, you need to adjust it to work in certain scenes. Real values dont always give the best results.

Hi there!

I am using denoiser, Intel one is very good but I cannot use it for animations, and Corona's one is slow but the main issues is that it messes up the reflections badly. And related to refraction, as soon as I turn it slightly on (regardless of refraction value, IOR, absorbtion distance etc) the render times tank :(
