Title: Frosted glass noise
Post by: robpayne on 2019-02-20, 18:59:19

Hi,

Is it possible to speed up the rendering of frosted glass using the GI vs AA balance or Light Samples Multipler? I have a very large (4500x9000px) image of a bottle to render that is mostly frosted glass. It cleans up nicely with denoising, but I can’t use denoising on rebus farm.

Any guidance will be much appreciated.

Rob

Why can't you use denoising on a render farm? It should be possible.

Increasing GIvsAA should help clean up noise in glossy reflections and refractions faster. Just don't go too high. I would check with 32, and 64 as a last resort.

By the way, I do not know what your scene looks like, but maybe you can get away with some other properties than glossy refraction? Have you tried using translucency instead?

You can but ONLY if you're saving to CXR

Try ranch computing, really good renderfarm
