hey Big Guns, i’ve been through all the posts on this thread, and i learned a lot, but the more you learn, the more you have to learn, so i guess its my turn to ask you a few things:
-usually people say you should apply sss materials on eyes to look realistic, but as part of a complex and physically accurate modeled eye, you’ll have at least 2 objects, the inner eyeball where the sclear, iris and pupil are, and the outer transparent surface, or cornea. so you apply the sss on the inner eye, and a standard vraymtl on the transparent exterior, or im missing something and you can use sss for the trasparent part aswell?
-you said you combined displacement with bump, but you also said you had only one detailing layer on zbrush, so what, more or less, is bump, and what is displacement? it would be good to know also how the cavity maps you mentioned works, like negative bump? and you emit hair from the sculpted cavities? that amuses me! i know hairfarm is a unique tool, but i had no opportunity to test it. i know it has also a unique way to “model” the hair, so did you model it and then converted to hair, or you used splines and traditional techniques?
-i notice you have a very simple scene setup for the environment, with a strong light on the viewer’s left, and a weak light on the right, that lights the shaded face of the character, but you didnt use a background to bounce a little light at all? the scene is just the character, camera and 2 lights? and also, when you say “no GI” you talking about GI disabled on vray settings, or just no environment light? because no GI would look like scanline or something lol
-about the texturing, i believe its probably pretty simple, since all the detail is on the displacement map, but i read something like using the sculpted beard to paint the diffuse texture, how did you do that? it would be amazing to see the maps you used, even very small versions of them, as it would also be amazing to see a render of the skin shader without the textures
-and at last, i know its hopeless, and that you don’t want to share your deepest secrets, but would be interesting to know your settings, like gamma correction, vray camera exposure, iso, etc (if you used them, or if you used max exposure system), your lights intensity, and the so wanted skin material settings.
i know, i know, lots of questions, but with your answers, me and many other people would learn so much! you don’t have to answer all of them, but please considering sharing a little more of your big knowledge!
thank you Luc, i wish you the best of luck
