Very nice tests Ryjo. One thing to watch out for, is that in the paper, when it says C_m = 0.5% (melanin fraction of 0.5%), then the actual fraction as required by Indigo is 0.005 (e.g. half a percent) Yeah, I did a fair share of mistakes during development of the scene, but I think I got it right ...

A bump map would definetly make the skin more realistic, but I don't have any :roll: Try This one... no "Heidi Klum - Skin" but should do the Job... http://img169.imageshack.us/img169/46/leath09kx2.th.png Your Rig really Kicks some SSS Ass ^^ My first Epi-/Dermis Test were horrible slow...

Yes, that's better^^ But: What are these edges in the skin? Is it, 'cause you didn't render it as long as before, this time? Do you mean the patterns visible on the forehead? Those are more visible the longer the render goes, this has rendered about 20 mins longer. It is a low res model, ~55000 ver...

You're right: except of the swollen ears and eyes, it looks too perfect. No idea, where you can get a bump map. 50 min? how much GHz&RAM? It's a core 2 duo (6600) with 2 GB ram. Here is a render using more asian skin tone (see page 7 in the spec). The teeth look more white now. The camera setting i...

Very nice render Dude!! a Bump map for the epidermis would be really great, or a backlight too :D After all, a very clean image... how long did it cook??? I'm looking forward to some more skin renders, this result is veeeeery promissing :wink: Thanks! This wip is from about 50 minutes. A bump map w...

Mhm, this skin examples are quite useful
I think, noone has a skin with 20% hemoglobin. It looks very unnatural..
Maybe, you should decrease the melanin blend beta/m value (This should make the skin look more asiatic, like the mesh...)

Yeah, I could try a different setting. Thanks for the input!

Maybe, the thickness is wrong at the eyelids, since they are very thin. Also the Eyes may give an other SSS value... But it looks quite realsistc, nevertheless... Yes, the thicknes of epidermis is 0.25 mm for the entire figure, which is too much for the eyelids. But its a test. The skin tone was ta...

Very nice pic! Only the teeth appear... yellow^^ The mesh looks a bit Asiatic, but the colour of the skin is more like n middle or north europe How is it lit? Sun? Thanks! I don't know why the teeth are yellow, they are defined to be diffuse white. Maybe reflection from the skin? The scene is illum...

Hello, Here is a head with epidermis/dermis surface/medium: http://i158.photobucket.com/albums/t110/gloriamundi_photos/im1171128989.png settings melanin_fraction: 0.5 melanin_type_blend: 0.5 hemoglobin_fraction: 0.001 epidermis surface: glossy transparent, exponent: 10 This was done using two mesh s...

This works since a while back:

A good way to start indigo is to use
This works on Win XP. It will put the indigo process in a lower scheduling class ("below normal") so the pc doesn't run so slowly for other processes.

The '-t' should go on the command line, like this:
... where 'scene.xml' is the scene to render.

You can also change the default setting in infile.txt:

So if I understand I should first multiply Sigma and Beta with a concentration factor. For example, if I want a 100% merlot concentration, I should multiply the value with 15,3, ist this right? I think that the concentration values are given as a reference (to repeat the experiment). The other valu...

I don't think it's the forum that is the cause, since the peak number of user ever is 34. That cannot cause 100 requests per second on the server. My guess is the gallery

ZomB,

I think your absorption_coefficient_spectrum is too low. This is what I get for Merlot:

absorption_coefficient_spectrum: 7.586 16.429 19.196
scattering_coefficient_spectrum: 0.053 0 0

I haven't tested this though...
