I have to start with a disclaimer. I'm only now learning Cinema4D and Octane.
Previously used the free octane VR with Poser and fell in love with it.

I've followed a tutorial on creating a blood vessel here: http://monovfx.com/tutorials/blood-cells-flow-tutorial/
(the project file is also for download there)

but for the life of me, I can't seem to get that nice soft skin light passing through glow on the blood vessel like in this image

Now, I've sat through the whole (nice) tutorials by inlifethrills on SSS and lighting and more.
But I'm getting nowhere, in the quest to create a shader that will render in Octane, an image close to the one posted above.
I realize post processing and fog etc might be added in post or the image itself generated by another renderer (possibly C4D's itself)

TL;DR
Would anyone have a heart, and create a shader - or give some tips/insights for something like the blood vessel in the pic. that I can deconstruct and learn from so I can learn how Octane would deal with organic SSS shading?

Cheers!

Hi,
why don't you have a look at the Materials/Organic/Skin section in the LiveDB?
The "tonysculptor Skin2" is surely a very good example ;)

That does look good. I remember browsing the Live DB earlier, maybe time to take a look at the materials again. Thanks for the tip.
Meanwhile, here's the disgusting material, I came up with

still hoping for that SSS effect of the first image.

Hi,
first of all, take care of the scale value in the medium node that is dependent from the geometry dimensions. In your example, the camera is inside the geometry, with a powerful light outside. Without backlight, is more difficult to see the SSS effect ;)

I've been a bit late in replying, buried in tutorials :)
Thanks for the extra tips and advice, bepeg4d
