Hi, Been close to a week since I've been trying to get the skin right. Finally, here's something which is close...not very real though. The lips are a bit dull, I modified the default Jessi Texture and didn't know how much red was right, so Oops! Well, it still ain't looking real enough, so if you guys can tell me whats wrong...would be great. Its based on reading Face_off's tut and a few other tuts on maya skin shaders. Here's the render, no postwork.

Here's another render, with a bit of perspective. Shows off Frensel falloff a bit better. Thanks.

A bit heavy on the bumpmap, IMO, but a good start. Keep it up 8-)

The best would be to mask out the lips or group them and assign a material so they dont get the bump. Too much bump overall for sure. I think a bump map rather than a proscedural map would be better unless procedural is your objective but without the map the palms and other smooth areas will be textured. Skin color just right. I have an old thread on procedural skin somewhere here.

Here is another render of the same scene. The Falloff is added to the object rather than the world. Any better. Face_off's GI render is great. Its just that I can't figure out how to get it. I think I got the bump right in this render. The aeyes are a problem now. Any tuts on getting that twinkle in the eyes? Links to: 1. Procedural skin 2. Reflections in Eyes 3. Environment getting reflected partially by skin would be welcome. This render lacks somewhere in the skin dept. I just can't figure out what. So plz tell.

That is looking realy good. Great bump. Only thing is there is a slight metalic look... contrast too high due to specular setting somehow? In anycase I would be happy to get such a render. that sheen is kinda sexy now I look at it more. Eyes need reflection or specular. This is realy nice! Procedural threads I started (N.B. These are before I got Face_Off Realskin Shader and I was wrong about it requiring too much RAM for my machine - I had worried bout the SSS and Fresnel): http://www.renderosity.com/messages.ez?Form.ShowMessage=2224971 http://www.renderosity.com/messages.ez?Form.ShowMessage=2220376

Attached Link: Specular Only Lights

That is looking good. I agree the bump looks right. Attached link is to a tutorial about "eye twinkle", especially useful if you're using IBL (I can't tell for certain from the image). Of course, you also need to make sure & set up the specular highlighting properties on the eye materials themselves (I think the tutorial assumes you've already done that).

I've got an eye glint mat pose package in my free stuff that works for me. It's mainly oriented towards P4 users, but you can check out the settings I used for the materials and get some ideas. The skin looks too desaturated right now in your render, the bump map is a bit too strong, and I think the highlights are too large - her skin looks like rich corinthian leather right now. Hope this helps some. Unzipped

OK...IMHO this is a lot less realistic than your previous attempt! 2 potential ways to get realism skin.... 1) Buy it!!!! This will save you soooo much time. Purchase the best skin maps you can find - pay good $ - don't go cheap - you get what you pay for. Purchase a Realism Script. Follow the IBL tutorial at the support web page for the Realism script (it's not the absolutely latest method but will get you 90% of the way there). or 2) Work it out yourself. Find a good refernce shot on the web. Load it in your favourite image editor. Blur it. Look at what colors are in the skin. You'll find they around R200, G160, B120 - and are a long way from the skin tone in the above image (R150, G125, B125). On almost all the skin on the ref image, red content will be high (> 200?). At no point will Blue be > Green. Study the highlight colors. Render until you get close. Then post here for comments. Eyereflections. Add a ray-trace node to the EyeTrans material in Jessi. But it will need something to reflect off. Use a dome around the scene with inversed normals and an IBL probelight image plugged into the ambient, or add some ambient lit props in front of the figure. Or easier still, use a reflection map insted of ray-tracing. All good Jessi texturemaps will have these (see my point 1 above).

Some of my best V3 textures were $5 in the Market place... I have spent some serious money on crap ones. I don't agree that the Sat is low. But maybe the hue is off? I don't think so. When I taught I taught to use Yellow Ochre, Raw Sienna, and Burnt Sienna lightened with white for European skin colors. Realy my only problem here is the slight metalic look due to the contrast... maybe softer lighting would help.

Ok, Thanks a lot. I will surely get it right this time.

looking great. Poser doesn't render pale skin very well. Shadows mixed with highlights turn grey and ashen. I would darken the skin and use brigher lights when required. I dunno if this helps but here are the colors I used for each part of the maps and the layer properties the later was set to when the color was put on that later. Regards, Anton Kisiel

It won't come out just like that but it is an idea on a direction anyway. Hope it helps.

Thanks! Certainly the diffuse colour is wrong. I will try to fix it. The problem is the lights change the colour a bit evry time. And its getting a bit like wax. And the skin is procedural, so don't wanna use specular n bump map. But I the brown colur ya gave for the skin would do the trick. Thanks a lot.


momodot ( ) posted Sat, 04 June 2005 at 8:44 AM

I use pure main gray spot lights with slightly bluish or yellowish infinit for sunlight effects. I try to use very few lights since my machine is weak. I have started trying dark dark brown ambient color as a "fill" even though I know it is not strictly realistic.
