Description

This is an experimental render, to test a theory. Before I go into the techo bit, thanks to Mitchell for the light probe of NY (eventhough it's a little hard to see it from this close-up). The experiment was to use an IBL light for diffuse, and then to use Stewer's poor-man's IBL script to get a bunch of specular-only lights in there - which matched the Diffuse IBL image. So the IBL map was loaded into HDRShop and converted into 20 lights (was a total illumination of 2). Then stewers script was modified to import all the lights are specular only. So there is 21 lights in the scene, and no shadows (but there is AO). You can see her teeth came out really well using this technique - also the spec light could be a little brighter - which would have helped the skin too. Her mouth probably needs a little more AO. Did the experiment work? Although her skin and features have come out nicely - there is no easy way to incorporate hair into this system. To render hair, the shadows of the 20 lights would need to be switched on (and do shadows work on spec only lights?) - which would increase render times from the 30mins this render took to many hours. So it back to the drawingboard. The texturemaps are all standard Jessi HiRes together with the P6 Character Realism Kit (out in a couple of days), except teeth (where I added some bump). Eyes had lots of node tweaking done to them. No postwork. I'd love to hear any crits that you have on this render.

generally, the image looks abit too washed out (tiny bit more shadows maybe?), and the lip corners look weird, but that's Jessi's fault lol teeth need more saliva (specular) too, maybe. btw, i welcome crits myself, i'm still new to p6 :)

Looks great. Fun to hear that you are delving into the technical aspects of P6 already. Can you make a shadow map using diffuse lights and apply that shadow map to this image? I don't know if you can render like that in P6 or not. I know you can't in P5....grrr Cheers

first off, great! IBL can be a pain and a wonder to work with! to the crits : shadows (lack there of) are what break this image, the highlights on the skin are great, but are not backed up by a darkening of the opposite angle that the highlights are coming from. you could also try upping the texture resolution for the IBL (if its a complex image) to get more detail into the IBL diffuse lighting... overall great work though

I think around the eyes looks fantastic... the lower eyelids and below the eyebrow. It's the teeth and lack of shadows? or proper lighting where the realism factor drops off for me. Also the nose looks a little "soft". Love your work though... keep it up! :)

I have never seen Poser teeth look so good. I love the blurred depth of field look also!

I love it when you do your experiments...helps us all!!! My very uneducated opinion is nature of the shadows...or lack there of, really stand out to me. Being an ex-photographer I've noticed that even in highly diffused light situations the shadows will still mold the face... Its really hard to have no shodowing unless, you're in the studio doing something like Robert Maplethorpe multiple softbox lighting setups. Nice work Paul! -jay

I think it looks really good!

I think it looks great, The highlight along her face is great but I also agree that more shadows at the left of her face will greatly increase the realism. It's a great Idea of using the script to create matching specular lights for the Ibl enviroment. I am also interested to know if shadows work on specular only lights, which I think they should not. I hope you get those lights working with the hair as well. Nice job.

Face_off! This image looks awesome, glad you had a chance to use the IBL I sent you....As Mahna stated, those teeth are beyond kewl, but then again you do such wonderful things to textures.... my only critique would be similar to Jay7347, you do need some shadow areas for a natural looking shot. talk to you soon ~m

I almost missed this one, Face_off. The skin looks really good, as do the teeth. I think I would have liked to see more depth to the eyes, however. The iris appears a bit to flat and dark for this close up. At that angle, I'd expect to see some hint of reflections and depth to the eyes, especially with that level of specularity. The lips also look a bit flat, and could use a bit of moisture as it does appear she is wearing lipstick, which makes lips shiny compared to the overall skin on the face. I really like this experiment! I wonder if all the extra lights were actually necessary though... couldn't a couple spec-only point lights, without shadows, be strategically placed to accomplish the same effect? Great work!!

While my keyboard gently weeps...Check your res on the eyes. They seem too crisp for this skin. They need a tad of red and an AO blur around the contact to skin area. I like where this is going...many outdoor shots have no shadows with all the bounced light going on. You really got the teeth.
