SSS material tests

You'd have to try this with the same model, to really tell this;) But I think, it's the same!

You don't need to go thru blender: just use the .ply file directly.

You've changed some things...
1) old:<rgb>0 0.45 0.5</rgb> new: <rgb>0 4.5 5</rgb> <- ten times of first absorbtion...
2) old: <rgb>0.1 0.5 5</rgb> new <rgb>4 20 200</rgb>
40 times SSS... the rest looks quite simmilar, but also the material looks fine, I'd say! You'd need to use the ToP Mod Mesh, for testring the differences...

And then it will work?

How can I position the object in the scene then?

I guess the problem with the colour really is finding the right combination and scale of the absorbtion and sss...

Still learning to handle sss. It's certainly not easy.

The topmod modell is about 1m thick, at the thickest point and 20 cm at the thinnest... just try to scale the dragon to these things (first try thickest 1 m, then try the mesh to be just 20cm thick...
1 BU = 1 m)

Hi,

I am new to Indigo and first: it's a fine rendering program. The idea of progressive rendering is nice.
I play a little bit with an SSS material rendered with OpenEXR lightning.
The result had a rendering time of 8h 25m on a AMD 3700 with 2 GB RAM.

Welcome homer_simpson !

Nice picture with nice SSS. A little bit dark however, you should correct tonemapping with Violet if you saved an IGI file.

welcome to Indigo, Homer^^
Nice SSS mat!
If you crank up the absorption, you could make tnit^^

tnit?

tint, I meant, but this doesn't exist, xD
It's Ink, sorry

Indeed, it does look like blue ink. Just needs a little bit more absorbtion.

Another tip: Lighting this scene with an exr is just waste of time, I think. A meshlight would hve resulted in almost the same render...

as far as i remeber my tests, exr lighting isnt slower than meshlight lighting.
@homer: nice clean sss monkey you got there

It is not? Nice to know. Thx. Never made extensive tests, I just assumed... (Note to myself: stop assuming and try it out more often)

But meshlights would be better to show the SSS effect.
Complex light looks more realistic, but it kills SSS

Oh! I thought you meant teenage ninja indigo tests.
