...while awaiting the next patch -- and the hoped for fix in the hair engine (Vibration with collision on) I am making long-render stills. With this one I got to know the effect of various GI settings on skin and hair and the SSS shader.

I continue to be impressed with the V4 cage. It is a fantastic model of the human female.

You have achieved some very realistic lighting effects on the skin.. still struggling on that one for me - always a challenge!  You should post this to your Rendo gallery as a larger jpg image.

I've never been succesful with sss in C, share some setting when you can.

will do over this weekend

there is an HDRI file in the background, as well as GI settings and SSS shader on the skin. I'll document when done

Same basic figure but a different personality and with black hair. This study is more about the body shape than the hair.

I'd love to know your techniques for the SSS too. Please share them with us!
Your work looks wonderful. The only thing that disturbes me a bit is the texture on the rug, looks a bit too large imho.

Yes, I just popped that rug into the scene and it might be completely stretched.

As for SSS, I am on a new learning curve for close-ups, eye relfection and SSS on faces. In the above renders, SSS is not a primary factor; most of the skin effect is coming from lighting with HDRI and GI plus the texture maps. I hope to write that up to a certain level over the next two days.

Thank you, GKDantas, I've downloaded the SSS and will try it!

I've had to put my SSS learning aside for a while because of another project. I spent about four hours with trial and error on a closeup portrait lit with HDRI and two specular spots. I've begun to get some good results on skin tone but not worthy of showing.

I am no one special in this realm, I'd encourage all to set up a test portrait of your favorite model and have at it with the SSS shader and various light combinations.
