It´s possible with the new SSS system make the single shit SSS like in the other engine??? For the leaves of trees, etc....... planes with no volume?

Thnx!
Mike

Sorry my english!

no it is not possible.. although it is not forbidden, you might end up with starnge results or artefacts...

... make the single shit SSS...

Single shit sss would be easy with some displacement, but never looked a shit so close to check if it needs SSS... for single sheet sss check Hervé's answer.

Sorry, although you apologized for your English I couldn't resist... aaaah somebody please delete this post

Yeah NL! Give us single shi............ oh now wait a minute!

Instead of "sorry", you should use "pardon":

Pardon my English
it might work better in your case

Hi there.

Here is my test of Maxwell 1.7 SSS.
I applied SSS to the bottle, lid and the liquid inside.
I rendered for 4 days with my Athlon 4800 but ended up with some noise.

Hi sjyie,

It might be because your model is not correct. It should NOT be possible to see the thickness of the glass next to the liquid if modeled correctly. Anyway, for transparent glass and liquids SSS will not make a big difference .

Hi Kurt,

could you help me in that thread

http://www.maxwellrender.com/forum/view ... hp?t=28911

to setup correct "glass of water"?

Thomas in his old thread

http://www.maxwellrender.com/forum/viewtopic.php?t=2906

suggests to model glass as an open mesh - but what about if you want to use sss material for glass? If I understand well - models using sss materials must be modeled as closed "waterproof" mesh to prevent odd results.

[KurtS]

hi MS,

actually, I support Thomas' method, and I've used it a number of times. It works perfect in my opinion. Thomas does not suggest to model the glass as an open mesh, what makes you think that?

[sjyie]

Hi KurtS

In Thomas' method, there is no glass in the contacting surface of liquid and glass. Doesn't that make refraction incorrect? I used a very small gap between the inner glass surface and liquid.
The reason thicknesso of the glass is seen is that the glass is a special glass with very low refraction rate.

OH Shit!!!!!

Pardon my mistake.......

Single Sheet SSS ?.So it´s not possible

Thks!

[Thomas An.]

No, not at all. When the engine encounters the second (enclosed liquid) surface it evaluates the snell law correctly from Nd-glass to Nd-liquid.

It is not recommended to use an air gap. In reality the liquid molecules bond so closely to the glass surface that there is no air in-between. If you model an air-gap the results will be incorrect.

Try this real life experiment. Take a thick glass and fill it up with sugar ... look at the sides of the glass and notice that you can observe its thickness. The sugar (being non liquid) has air trapped in between the grains as it touches the glass surface.
Now, empty the sugar and add some tea in the glass... you can no longer observe the glass thickness. The difference is substantial.

I do not want to mess up this sss related thread, so I answer that question in "glass of water" thread.

..the new SSS is really amazing! I love it...

some of you might recognize this, it's the yang-touch lamp by Artemide.. the original looks like this: (FOTO!)




i think it makes a perfect sss test object;

what you see here is just a quick&simple material test with a model that still lacks a lot of details (cabels/wires/circuit boad/switches/reflectors etc.).
when i find time i will transport this to the WIP section and do more modelling.
The aim for the material was to create an acrylic glass with the use of SSS.
I made a material combined out of A BSDF (90%) and a SSS layer (10%) derived from the polyurethane preset.
I still have to play around with the transmittance, cause I think that is where i pick up too much color (solid cylinders in the center)

..besides my color issue I am very impressed by the new SSS system except for these uninvited guests who happened to turn up at my party:



I had to kick them out ... but only by postEd: (just simulens +scatter + dot removal)

[Bubbaloo]

Nice! Is your mesh closed? You may get black dots if it is not.
