Blue SSS with randomwalk on model with red radius

Greetings to all.

I'm trying to use the randomwalk SSS mode to shade some human skin, but I'm seeing weird artifacts near where the clothing meets up with the skin and also around areas such as the toes and fingers.

I've attached a picture of the problem. The radius is set to a very red color (with no texture currently attached to that port) and the scale parameter seems to have little or no effect above and beyond throttling back the SSS effect as a whole. I'm not sure where the blue is even coming from- it's quite puzzling.

Does anyone know why this is happening?

Cheers,

This is an error of the rough SSS method in Arnold. to explain what happens: open any photo (human face) in Photoshop

- go to chanel - select = R

- Filter - Blur - Gaussian Blur (set radius 10)

- go to chanel - select = RGB

and you can see how SSS work in Arnold.

not know... how long wait fix...
