Tech Renders / Subscriber Renders.

Thirty Days news coming this weekend, just wanted to share these with everyone.

So I was working on setting up a scene the other day, Its an Alex solo scene, and was having a personal issue with the lighting.   Well more the way the skin reacted to the lighting. So I did some adjustments, worked on some new settings to allow spectral rendering, and I must say, I am pleased with the outcome.

This is not a shader and setting set I can use a lot yet until I get more hardware after steam release, but really look forward to working with these settings more.

you can really see the details in the image with Alex in the black dress and the closeup of Kayla on the bench.

The 2 almost identical renders over Kayla's shoulder looking at Alex, This is why I cant use these settings a lot yet. One of the renders, looks unfinished and it ran for 40 minutes on all 4 cards. Then I turned on a luminance limiter and ran it for 10 to get the other image, and I really don't like using that limiter because if you look at the 2 closely, the unfinished one has better light reaction and detail on the skin, as soon as I set the limiter that is gone.

The reason I did all those just to test the new shader?, Well I wanted to give you all something :) and every time I work on a new shader and it looks great, under different lighting conditions it will very drastically, so ran all these to give you guys something and to make sure this shader works in most conditions.

I love spectral rendering, plan on using only spectral rendering after steam release because it is demanding. The difference in spectral versus normal path tracing is normal path tracing just traces a single path with what ever color the light source was, Spectral runs 3 paths, 1 for each Red,Green,Blue value, better color and does amazing things for skin because skin is all built on sub surface and dual lobe spec. so the specular rendering does wonders with that as the light hits the skin it will absorbed different amounts of each R,G,B value giving a more accurate representation.

Would like to use the caustic sampler more as well, but that one is even more demanding and I think is a little broke. Not sure whats going on with it but when I turn it on one of the 3070's usage is maxed out, the other is at like 60% and the 4090 averages about 35% usage, not sure why but multi gpu rendering doesn't seem to work with caustic's at the moment.  Caustic sampler mostly helps with glass and metal, also does help with eyes.
