Skin shader with SSS

[sigmamoon]

I quickly turned off the front light and up the sss effect - and you can see there is some ear glow.

After that I played with the cone and emitter in standalone - comparing 1.00 with 1.10. They are different. Firstly I needed to disable alpha-shadows. Also, check your rayepsilon isn't wrong for your scene size. The maxdepth makes a HUGE difference. If you want strong sss in the ears, turn maxdepth down to 3 or 4. The higher the maxdepth, the more the sss bounces around diminishing the effect.

Another thing - SSS skin shaders mix a glossy and diffuse node. So the sss effect from the diffuse node will be diluted by the glossy.

nice fall_off

you said you compare between 1.00 to 1.10, do you have try with the v1.11

Not standalone. But that render above of the head was done in 1.11 (current Poser plugin build).

BIG THANKKKK YOUUUUU "Face_off"

you give me many great informations to swap between the v1.10 than v1.11 SSS

some of your parameters work in the standalone too, i ll make a video to explain for the communoty soon. But, in final rendering i have a really noisy result (the v1.10 was really quick to blur all the artefacts)

do you have this feeling?

and roeland from the octanerender team confirmed there are some SSS problems with transmission. that s great to discuss about this problem to make involve this great render engine

Nice to share with you

I noticed a lot of noise too - so set hotpixel_removal to 0. Increasing caustic_blur would help too.

Thank you face_off

same here!

i hope the octane team could involve this part cause i loooove the scatering medium

i ll make soon a little video for newbies "like me" to help to swap from v1.10 to 1.12

i like your website "face_off" and thanks for your exchange.

Sorry for late reply.
This is looking much better now, I can test this next days and report my results.

Thanks face_off, mib.

Thanks. Finally had a look at this and manage to reverse engineer it (I think).

One with a couple of lights, and one with daylight. Not perfect, but much happier with it.

The skin is a bit too glossy in those last images.

[gordonrobb]

Funny, I was thinking that around the side of the head, it wasn't glossy enough. However, definitely too glossy on the lips. Trying to understand node system in Lightwave enough to see how I can use the 'glossy' image from the model to have the lips be different, but reducing the difference, while using another node to control the overall glossiness. It's a journey. But compared to where I was with this last week, I'm over the moon

I like those. I think they look great! I'm going back to the drawing board after looking at your work.
