    LightWave 2020 - Random Walk SSS

    Hey everyone,

    I don't often post here, but I was so keeno to try the new 2020 Random Walk SSS that I did so this morning, and this is the result.
    It seems it's really hard (or impossible) to get a blue base surface blending with an orangey colour (i tried in Blender too, and it's just not possible), as it's technically not physically accurate.

    ... but after a bit of effort and using the SSS component material nodes, I came up with this. I personally really love the LightWave renderer, I think it's gorgeous.

    Yes, I totally forgot about the Nvidia Denoiser... bear with me, I'll do one with that turned on now...

    There you go, denoised and half the render time too. I didn't realise I'd accidentally changed the Adaptive Sampling to 0.0 Oops!

    Yeah, not sure why the denoiser doesn't remove those. Maybe it's area light sampling?
    Trying another render soon.

    Looks like you need to crank up the SSS samples in the Render Properties. But I really like the look and the material you've created.

    Test number 3.

    I am working on a remote desktop connection, so can't seem to see some of the blotchy bits from here.
    This new test I've used an iridescence fresnel for the specular. Know it's completely non-physically correct, but it does look pretty neat to me. (I reduced the distance of the SSS too, as I think it was a bit too much really.)
    I also increased the samples on the area light, just to see if it helped with those blotchy bits you could see.

    Cool! I'll have to download the demo and give it a try. This would be the main reason for me to upgrade. How long was the denoised vs regular render? Looking good!

    I think the top one was 8 minutes, but I messed up the settings and didn't realise. The denoised ones were 5 mins. Denoising doesn't take any time at all, literally seconds to do. Not tried Denis P's Intel denoiser yet either, and that's supposed to be even better.

    Thanks guys... not my model, but hey, it's good to show stuff.

    I have rendered an animation of a spherical light spinning around it, but it's a bit noisy. Might share if there's any interest.
