Just play with the size of the texture by adjusting the multiplier and the depth/height my changing the divide setting on the output of the texture. I currently have my divisor set to 800 and decreased the multiplier to make the texture a bit larger and at the same time less depth. You will need to adjust to taste.
I had a bit of trouble with the backscatter on your setup when there is a light behind the head of my model. The whole head turned red instead of just the ears. How did you solve that?
Ah, do you think you could show me the node setup for the bump?
As for my subsurface I also get some strange results depending on the lighting which is why I am looking to improve my skin node setup.
and especially here:
I get a strange “glow” coming from her neck and shoulders. I think the only thing keeping it from coming through her face is her hair mesh.
I did rearrange some of the nodes in my skin shader when I made it because I found the “glow” to be worse in its original form with suzzane:
have a look
I wouldn’t really recommend it for use though unless you need something temporary.
