Softimage and good skin renders
Hi
I have been wondering and scurrying the net to see if i could find good examples of realistic skin rendered out of softimage. They are some fantastic artists doing great work in softimage However there appears to be a disparity between the skin shading quality coming out of softimage versus renders I have seen done in other packages.
If you have any good examples please feel free to post them in your reply

Re: Softimage and good skin renders
a bit out of the context but, just for the eyes, rendered out of softimage with the arnold renderer

Re: Softimage and good skin renders
thanx for the example unfortunately arnold is not available to the masses yet AFAIK
Re: Softimage and good skin renders
there are come on cgtalk/choice gallery (misss fast). But of course most come from 3ds max.

Re: Softimage and good skin renders
I can think of many good examples of human skin created and rendered in XSI over at least the past 5 or 6 years. Most of them were posted on xsibase although it's unlikely that many of the images would still be available now, not to mention the fact that searching for anything on xsibase is pretty much futile.
The other issue of course is that in very few cases has anyone ever been willing to share the specifics of their human skin shaders, scenes or lighting setups which is a shame.
The topic of human skin is of particular interest to me and following developments with it has been something of an obsession of mine over the years. All I can tell you is that yes, there have been good examples done with Softimage and it certainly is possible achieve.
Cheers,
Joe

Re: Softimage and good skin renders
We have a project in development that will require alot of skin shading and we love xsi. However it seems to be lacking in the area of skin shading compared to maya and max as far an mental ray rendering goes. Although its the same renderer which is weird imo. I am basing this on results i have seen just googling and browsing around the net and popular cg forums. We have been also looking at vray which is looking pretty impressive.

It might seem that way only because more Max and Maya people tend to share much more but the truth is that there is no real difference anything that you can do with Max or Maya can be done with Softimage.
Again, Softimage users have as long as I can remember (which is a long time) been very bad about posting images.
Good skin quality skin can certainly be achieved with mental ray, Softimage and some knowledge.

Re: Softimage and good skin renders
From public available renderers, probably most 'accurate' skin shader is 3dLight's one. AFAIK it's based on (relative) 'physicaly plausible' method, and it considers ' subsurface groups' as well (it's able to avoid internal surfaces that you don't want to scatter, such as eyeholes, mouth, etc.). Check out for examples, here, and here.renisancex wrote:We have a project in development that will require alot of skin shading and we love xsi.

From out-of-the-box stuff, it's the same mi_SSS_Skin as in other two Autodesk's 3d app - based on 'cheap trics' (blurred diffuse shading + biased gamma + back translucency, something like that). You probably know that words 'epidermal, subdermal' in PPG of this shader, are nothing more than just words. I think it's really hard to talk of 'quality' of this solution, as it can look great sometimes, but also completely wrong - anywhere.
Generally, it's possible to get the similar effect, using ICE on vertex colors...
Fact is that Softimage implementation, sometimes, has a few problems more ('double additive' in mi_sss_skin compound, at least sometime around XSI 7), but there are also a lot of fixes/improvements by Softimage community.
It seems to me, there were more of human skin renders a while ago, in times of XSI 4, 5, especially using a famous Diffusion shader by Daniel Rind. Who knows.. maybe authors were found their jobs in meantime. Where I works, last time I saw the demand for realistic portraits, it was done by Photoshop guy in fraction of time needed for 3d version (It was a bunch of portraits of heroes for video games). If you want to animate it, realism became a problem, you have to add the correct motion to every damn wrinkle or whatever... In big productions, you'll already have a help of TDs...

I don't know exactly the qulaity that you are looking for, but if you need some information the link below might help. The information is older, but knowledge never hurts. You might be able to find something in the link that may be useful.

Re: Softimage and good skin renders
probably best skin I've ever seen. So this example shows that shader is only part of success. Model with (ultra)detail and textures are probably more important.NNois wrote:a bit out of the context but, just for the eyes, rendered out of softimage with the arnold renderer

At least it's working in multiple light conditions, and it doesn't look like a wax model like 90% of cgtalk choice award images.
It seems that everyone loves to exaggerate sss effect.
Re: Softimage and good skin renders
If you want to try Daniel's Rind Diffusion shader you can find it here http://www.rray.de/xsi/
Re: Softimage and good skin renders
Lee is pretty smitten with Arnold and it's skin shader. The shader does make a big difference.

This is worth taking a look at. Its the same head model and textures rendered with lots of different shaders and renderers.

Re: Softimage and good skin renders
Of course it makes difference, it's visible how mi_sss_skin tends to look 'monochrome'. Correct shader is neccesary component, together with textures and geometry. One bad component can destroy everything - all three are important...Pooby wrote:The shader does make a big difference.

Re: Softimage and good skin renders
Thanks guys
Yes it was evident to us that there seems to be a different implementation within the softimage version. Even when using the mental ray phen version in xsi 2011.5 it gives you different results compared to the softimage Fast skin
Thansk for the cgtalk thread some of the images there are pretty well done.

Re: Softimage and good skin renders
This was rendered in 3Delight by Kissb (xsibase); I think it's outstanding!

Re: Softimage and good skin renders
Well I think we would never see Arnold for mortals. Even their website is on construction. Perhaps if we "mortals" gather to make a full animated 3d feature film in SI we can take a test drive. Someone who is interested in putting some bucks on it?
But never mind the world is ending in 2012 as the Mayans said...
The only thing I really hate about MR in Softimage is FG in an animation sequence. If some one can tell me how to get the goddamned flickering in some scenes when the camera is moving with descent settings. I am tired of appending points to the map, freezing it, increasing the rays, turning my chair 2 times to the left then 3 times to the right. Pulling out my hair... It is still there...
