Re: dark juice

Caustics shouldn't be yellow? They are in the darker areas, but not from top edge. Can it be the bright light is clamped or overexposed with linear tonemapper, because sun brightness in exr file is 10 000 000 000 or inf (the original hdr usually has floats under 200k). With gamma 1 it's 10 000 000 ...

Re: dark juice

It feels little too yellow and OIDN went very bright, so i post raw image. Absorption has to go down.

Re: some preview bug?

Epsilon settings maybe.
What is the size of the triangle face, epsilon value can't be too far off from that.

Re: dark juice

Interesting, is this just bias, or there are indeed more SDS paths inside scattering volume :roll: What a huge time gap between 10 min and 9 hour render. The smaller radius has no scattering volume effects, but renders so long. bidirvm sds bias vs time.jpg ------------- EDIT Nevermind, i got the vol...

Re: dark juice

But the juice absorption is orders of magnitude 100 times stronger. How can you see transmission color if environment reflects light 10 to 50 times stronger. Disney specularity set to 0.01 and roughness to 0.4 and diffuse to 0.2, even so the specular reflection is dominating.

Re: long triangles

Bevel modifier???
See if you apply it, are there any weird overlappings or onmanifold edges.

Re: dark juice

Speaking of the dark areas, in juice / hetero volume. Now my setup with bidirvm is: startradius 0.05 alpha 0.25 lightpath.count 65536 (note here with 256 to 1024 the caustics are much sharper, but sss effects weaker when radius is small). Light setup is hdr map with gamma 1 + 2'th copy with gamma 0....

Re: dark juice

here's cycles, I don't like the juice look but it demonstrates how it never gets darker in glass (this is without disabling shadows or anything) by the way, enabling photongi indirect will make it even darker. The BiDirVM random sampler render (manual linear tonemapper) i did overnight, had opposit...

Re: dark juice

The bidirvm looks little better, but it covers well only with huge bias radius and the bias will not go away with no strong alpha 0.75 or lower. It seems to render ok with radius 0.01 (insane bias) to 0.001 (sharp ok, slow effectivity), but the alpha 0.75 will take it to too small radiuses. Maybe vm...

Thank you Fox!
I'll try to play with it when I find some time.
The converted orange juice values in old Indigo manual are very low, i guess it's lemonade like fanta.
