I confirm lacilaci's finding, that Glossy Translucent doesn't work together with bump maps. It works with the June 26 version of LuxCore, but does not with the Aug 8 version. Matte Translucent is equally affected. It can be reproduced with example scene Procedural Leaves : https://github.com/LuxCore...

Looks good, thank you!

(I'm away from my computer for a few days. I'll test it when I'm back.)

Thank you Fox!
I'll try to play with it when I find some time.

... I'm convinced LuxCore is doing the volume thing physically correct but that means tracing billions of bouncing paths in a dense scattering medium, together with the very low efficiency of SDS resolving with BiDir/Path+Metro it is taking its toll on render time. ...

Do you have a formula, that can convert these values to LuxCore volume settings (and not just asymmetry but absor...

I just realized that path depth is the most important part with this juice case . Below are renders with Path / Sobol (without light tracing and any other "tricks"). The settings are the same, except path depths (total, diffuse, glossy and specular depths are set the same per render). Rend...

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 w...

no, they don't look nice, it looks wrong. Does this look like to you it would in real life? I don't know your settings, but I like my results, e.g. this one: (Sun+sky light only, BiDir+Metro) http://forums.luxcorerender.org/download/file.php?id=5508&mode=view With some brightening and color bal...

You can see, that the Sun and sky versions look nice too.

And, indeed, dark ground does help, because orange juice can't really be brighter than white.

Yes, I didn't "shuffle scene, camera and lights around to make it look almost like what it's supposed to and call that a solution."

I just tried simple, proven environment, and it looked good right away.
