Hi, I tried this render with an arbitary pic to set up the IBL and just seeing how much I could get the Lighting to Match what probably real light in such a situation would look like. Tried four new things: 1. IBL with custom Pic 2. Getting the Skin to look good with the IBL 3. Trying to get the environment to bleed onto the skin 4. Getting some sort of realistic reflection of the environment in the eyes The IBL seems OK, the skin I will never be able to get good unless I see someone's Material Room Setup or a .PZ3 file. So help. The reflections in the eyes didn't work well. Perhaps should have used map with more contrast. Any links to tuts on getting the skin good(Perhaps like face_off's renders, or even 1/5 of that) are welcome. Suggestions on improving the pic(what else needs to be done with the skin. Can't figure that out) welcome. Face_off I tried rounding off the specularity and it still didn't work! So help. And if someone knows any tut on Depth of Focus, please provide link. I can't get it right. (And I wanted to post a larger render, but the 200kb limit :( )

Attached Link: TUTORIAL : How to achieve more realistic skin textures in Poser 5

Skin: See attached link. That's face_off's tutorial on setting up really great skin shaders. Face_off also sells a set of python scripts that make that setup very simple to apply. It's sort of complex to do it by hand.

Reflections in eyes: You won't get any specular highlights from IBL alone. The simplest way to fix that is to add a light to the scene, pointing the way the light from the IBL falls, and set it up as a "specular-only" light: In the Material room, select the light and set the Diffuse color to black, and the Specular color to white (or whatever color the light is).

If you want more detailed reflections, I haven't tried this, but I suspect that if you have a spherically-mapped environment you're using for the IBL, you may be able to take that same image and plug it into the Reflection node on the eyes, for a quick environment-mapped reflection. Like I said, I haven't tried it, but I believe that both IBL and the reflection node take sphere-mapped environment maps, so if we're lucky, they'll match up...

Regarding reflections on skin....I think that skin has very low reflective properties - it only reflects quite bright light - and that it catered for by specularity. Also - getting the environment to bleed into the skin....either a bunch of colored infinite lights which match the environment, or an IBL will do this. If you are serious about skin realism, you really have to start with a high quality texturemap and (more inmportantly) bumpmap.
