Absolutely great:bow: :bow:
How did you paint those textures did you use projection in zbrush or did you paint it by hand?

ok - decided to try out the msss_fast_skin_shader. i'm using the mix20layer shader from pixero.com with the msss_fast_skin shader and a blinn for specularity. everything still needs a bit of work so ignore some of his craters.

i've been following a tutorial from gnomonology on skin shading. however i'm having some difficulties attaching the displacement map. I figured it would be plugged into the mix20layer's shading group, but nothing seems to happen. i also tried adding it to a separate blinn that i add as an overlay, but still no luck.

any ideas?

here's a copy of my shader. i figured the displacement map would just be dragged onto the mix20layer or manually attached to the shading group, but when i try to render, nothing happens - the screen stays blue and the status report comes up.

help!

Hi Arran

You need to connect the displacement map onto the blin and onto the SSS, in the SSS its in the shading group (I think, have a search through the inputs/outputs of the SSS) not in the SSS attributes directly.

Hope it helps

hmm - thanks steve - i tried various combinations, adding it to displacement mat. under shading group attributes and to displacement shader under mental ray on both the sss and the blinn, but still no luck.

i've been using the regular displacement node under create maya nodes, cos i didn't see anything under the create mental ray nodes - would that have something to do with it?

ah! - it's 4 AM here so i should probably get some sleep on it and have another look tomorrow. thanks again.

hey - thanks starjsjswars

yeah - the facing ratio is plugged into a ramp on the blinn's reflectivity to give his skin a touch a reflection on the edges.

will post an update when i get the displacement to work.

Nice going, Arran.

I did that tutorial too, very good one. Although there is no mix20layer in 64bit so I got stuck on the diffuse since I couldn't understand that specular thing in the miss_fast_shader...

hey - thanks djblazer! i'm wondering if you can use a layered shader instead of a mix20, as it's only 2 layers. i don't know how many layers you can use on a layered shader though or even if you can use a sss in it.

just managed to get the displacement shader working - i ended up just using my first displacement blinn. everything still needs to be tweaked - especially the bump which is creating some craters - but i'm just glad it's working even if i don't know why...

Good thinking, I'll see if I can use the layered shader...

Looks good... although this, and the previous images looks like the bump/displacement/color or something is very lowres... he looks a bit blurred..
