Skin and beard shader, please help me!

[prozac93]

ah, i have another issue, if i set the displacement to 2px  it render instantly, if I try to go down like 1.5 it become very slow and it take hours to start the initial pass, any advice to get a good displacement without taking all that time?

2px to 1.5px in displacement has impact to RAM but imho it wouldnt be that far different (take hours with single character rendering). Did you receive a warning about running out RAM? Because low RAM can kill the rendering parsing time

[prozac93]

haha.. yes, every time, I just ignore the message XD , with 8 giga of Ram i don't expect to have high performances

[Christa Noel]

Haha, i hate the time when i face a low RAM problem too
if i'm not wrong i remember that somewhere here one of corona team said he is planning an improvement of memory management or something like that

Memory optimizations are on the roadmap, https://trello.com/b/EfPE4kPx/corona-road-map-3ds-max - best place to check for what is in the pipeline!

Ok, subscribed your trello now :D
Wow geometry optimization is on the way now:D, but does it help corona displacement to consumes lower memory?

Any advice to make the skin looks softer?? SHould I use both translucency and refraction?

[sprayer]

maybe try to reduce bump value, for me it's looks like have tone cosmetic powder.
And no you should't use refraction for skin because it's not have IOR.
Do not like glossy horns(

you are right, maybe if I blur the displacenet it could be better?
The horns material has 40% glossiness, is it too high?

[cecofuli]

IMO, you should "break" the glossiness between  horn and face.
It's stange that the skin has the same specular level of horns.

This.

I'm by no means a 3D character expert (I can't even fathom modelling what you've done!) but from checking out a few 'making of' videos the most realistic ones use hand painted reflection and gloss maps (as well as skin pore maps). For example the bridge of the nose and forehead is usually fairly shiny on most people, but the side of the cheeks and eye sockets are quite matte.

[prozac93]

thank you all for the advices! I really appreciate

[romullus]

Of course it has, everything has index of refraction. I remember i read somewhere that actually skin has quite high IOR - over 2.0, but i couldn't swear on this exactly. And yes, to use refraction for skin in Corona is perfectly valid method. I tend to use translucency, but mainly because i hate how objects displayed in max viewport once refraction goes below 1.0.

[prozac93]

Another test, this time I added some estra cavity texture on the horns, drastically decreased the reflection and the glossines  and increased the displacement. I also decreased the displacement on the skin and added some grainy bump

[prozac93]

too much diffuse I guess..
