Purespider. There seams to be some common problems with sss.

CTZn: the glass material is a simple specular no sss on it.

Polinalkrimizei: Thats what i tought to....

Hope ono can shine some light on this

[CTZn]

Okay, too bad

You are correct Polinalkrimizei, though, being different unbiased rendering techniques, each has its drawbacks, and bidir is only one step in the struggle of path tracing against nuked pixels (its very drawback I suppose).

Now, if that glass in the middle of nowhere then maybe the lighting is not "standard" enough, might be crucial for sss (sun is a small lightsource after all).

[Stromberg]

I did change the light source, to a bigger one...
Rendered with PT and BiDir for about 2 hours.

Motor oil mixed with caramel. Or maybe pecan pie filling? Either way, Mmmmmm

[Stromberg]

It looks more like motor oil right now then juice
Thats why i'm going to leave the juice rendering to suvakas the one who knows it

[CTZn]

Try MLT alone ? It will be weird for a moment, but with time... I seem to remember that suvakas affectionates simple MLT

Ah blame me, I told you already. Am I noy getting old ?

At this stage if you are stuck with nuked pixels, you want to set supersampling to 2 or even 3 to disminuish their impact. They will always be of the size of one pixel so the higher the res the less annoyance.

There is perhaps something to fix here, this issue tend to appear with intersecting mediums, not always, but notably with the documented glass setup.

Tested against 2.0.8 ?

[Stromberg]

Tried with 2.0.9 i think.
I gues this is a problem... but what do i know

Arne told me he had that bug with the mat test scene and milk aswell...
See this for reference.

Hey Stromberg,

What are your settings for the orange juice in your latest render?

[Stromberg]

Here we go...

Seams like it wasnt of any help

Well here is a motion blur test, and one volumetric light test.

[Stromberg]

Tolas asked me if i could render he's lamp with indigo. He seamed to like it
Hope you will aswell
(Remember model not buy me)

[Borgleader]

Haha that's a cute scene

[Stromberg]

Thanks
Yeah, i was aiming for a fun/cute scene
