Subsurface experiments

Hi guys,

I have been playing a bit with the subsurface scattering options of the upcoming release, and it's time to take this out of the Alpha section

Here is a little jade thing:

Looks great. I have about a hundred different translucent stone and crystal setups that would look great finally with better subsurface scattering.

Request A good test would be a wave, with you know scum on top breaking up the light into the water interacting with the wave shape. I Haven't seen this done and it seems like a go-to for TG.

What a cool look! Like!

You have a way with materials

Ahhh, this is satisfying to see. No more hard shadows where should be some light. Would be nice to see some veinage.

That is another really fine example!

That's gorgeous!!!!! You're indeed the SSS pioneer!

I can't wait for this feature.

Do you mind sharing your experience on render times, and what works well in terms of settings for a good balance of quality versus render time?

KyL · October 21, 2019, 08:49:07 AM

Sure. Render times are actually in the filenames of the pictures so if you open any of them in a new tab you will see the render time.
Usually it is between 30min and 1h to get a nice clean 2k image on my machine (threadripper 2950x with 32 threads)

In general I render using AA6, as most of the objects I used with subsurface are quite smooth and not very challenging to sample. I increase the number of path to 64 to get a nice clean subsurface. For animation you could probably go lower.

not on my computer in Google chrome..just an index.php and the size
