Re: Sub-Surface Scattering

That looks quite cool. I'll experiment with it, thanks.

Re: Sub-Surface Scattering

Good points. Maybe a specialized fluorescent material would be a nice addition to LuxCore's material types?

I agree that getting SSS to look the way you want is right now very hard and should be improved. I think the best course of action would be to extend the disney material implementation with SSS support.
That'd be great, thanks!

Re: Sub-Surface Scattering

OK, no problem. It would just be slightly more convenient if you could plug in a color you're already using for other inputs.

Re: Sub-Surface Scattering

One more thing: I'd love to see a color input slot in the Material Shadow Color:

Thanks.

Re: Sub-Surface Scattering

BYOB, would it maybe be a good idea to insert an energy multiplier in the volume node, to emphasize the SSS effect? And/or maybe implement an additive mode, so there will be brightening instead of darkening inside a volume? If I'm understanding what you are asking, it would break the energy conserv...

Re: Sub-Surface Scattering

Hi guys, Tried the SSS example scenes, many thanks, BYOB and Sharlybg! The scenes gave me some valuable new insights into Luxcore SSS. Sharlybg, I'm curious why you used an Invert node in your SSS setup: Image 1.png Does the Scattering color absorb that color inside the volume, in stead of scatterin...

Re: Sub-Surface Scattering

Thanks a lot, B.Y.O.B., much appreciated! I will have a thorough look at your scene tomorrow morning. Yeah, the SSS Radius is an RGB value. I often plug the color in that slot as well, to emphasize the SSS color, as the RGB node has a three-fold vector output corresponding to the SSS Radius RGB chan...

Can you just make a simpe scene of your Cycles SSS applied to luxball so that we can just convert it to Lux for you ? :idea:
There's no special node setup. Here's how the SSS material looks in Cycles:

Thanks in advance if you want to give it a try.

Re: Sub-Surface Scattering

:) Yeah, but I love the gradually diminishing, glowy light as surface depth progresses in Cycles. I tried all advice I've read and viewed, and just don't succeed in achieving that effect in Luxcore. Either the whole surface gets lighter or light doesn't penetrate a surface enough. But I've sent my s...
