I'd buy a pack of juice and shoot a reference, but I currently have no sun available and probably won't have for few days.
But we know already that luxcore currently has no way to make diffuse volume in a glass right.

Re: dark juice
You don't need reference, everything will be just fine if the issue gets a fix...
here's a better illustration of the problem,
glass invisible to camera, volume only: so you can see the glass is completely overshadowing the volume
and just for fun if we enable lighttracing, we can see how things should go within the volume(of course it only works with glass disabled so we don't get sds)
Re: dark juice
another example, here you can see that the juice in the glass is actually even brighter thanks to caustics from glass, the only thing overpowering the brightness should be bright reflection on the glass and definitely no weird shadows.
Re: dark juice
I don't know your settings, but I like my results, e.g. this one:
(Sun+sky light only, BiDir+Metro)
With some brightening and color balance it would look something like your reference image:
Have you tried Bidir+Metro?
Re: dark juice
did you just completely ignore this part?
here you have it in 4K, on the left that's how it needs to look when it's in glass!
I'm not discussing if you like your results, I don't care about half working bidir, about hdris, about postprocessing.
I want my juice in glass to look good correct under any lighting conditions straight out of luxcore as fast as it can, cause that's how it needs to work.
Right now there is clearly no way to render it properly and getting good results without going through weird limitations is not possible as it seems.
Afaik, other renderers use some shadow tricks for glass, if that's what is needed then so be it. If there is a better way (actually better not one that will require me to do some circus tricks) then so be it.. But now it's not working as it needs to.
Re: dark juice
Just for the record, it works with built in Sun+sky, without HDRI, from any angle, straight out of LuxCore, without any tricks and post-processing.
(I only mentioned post-processing, because my render is darker and has different color balance than your reference.)
Yes, it currently only works well with BiDir+Metro, and it would be much better if it worked with path tracing (and GPU) too.
Maybe is it something with OCL? I don't have discrete GPU, so only tried CPU.

I just can't get that bad results. Would you share your scene with the settings?

Re: dark juice
I don't know how to respond to this, what works? If those results you get work for you, then great, I'm happy for you. Good luck..
Again with this bidir+metro... Bidir itself isn't working well, it's slow and no matter what you say it won't do sds, they will never converge properly.. I don't want to hear about bidir.
I'm using your own scene that you shared 2 or so pages back. I literally just flattened the floor so that I don't get some back bounce light and copied the glasses, that's it that's the scene. CPU or GPU renders the same.
But I spent already way too much time on this, so for the last time.
If you're happy with what your'e getting, good for you. I'm not happy and I know that it works differently in other renderers so the question is if it can be fixed. For that I guess I have to wait until Dade comes back home.
Re: dark juice
Maybe this would work http://iliyan.com/publications/VertexMerging
or this https://graphics.pixar.com/library/Cau ... /paper.pdf
and this I think claims to be better than those above https://www.academia.edu/20210556/Unbia ... Simulation.
Also mister Hachisuka has many interesting studies on differents matters https://www.ci.i.u-tokyo.ac.jp/~hachisuka/

Re: dark juice
Please, then show some comparisons to "juice" you've done with other engines.
I'm interested to see facts about how much they differ from your experience.
I realized there are flaws in all engines quite soon. Almost immediately after every new beginning. But now, after years, I kinda started to feel good about the development overall and planned advancements. So let's stay on track here... ... optimized, better materials are the next level. Another best thing to come soon.
And here's my go:
A Filmic, high contrasty Dark Juice surrounded by Disney's Metals... but the Pills are M.I.A.

I believe that what makes artist the Artist, is the fact that it does its best with whatever tools it has at hand. And doesn't put the blame on its flaws for own misfortune. Remember, high expectations brought Icarus its demise. Or maybe I'm always wrong
