VRayFastSSS2 in Raytraced (solid) mode, less refraction, how ?

Hi,
I use the VRayFastSSS2 in Raytraced (solid) mode. The problem is : when i use this mode, my material is “too transparent”. I don’t want to change the intensity of my lights.
How can i set my material less “transparent” ?

It looks like, in Raytraced (solid) mode, the Scatter radius doesn’t work ! Is it normal ?

Thanks.

Scale parameter does nothing also ?
So, when we are in Raytraced (solid) mode, we have control of…nothing ?

All this works fine for me. If you have a scene where it doesn’t, you can either post it here or email it to me at vlado@chaosgroup.com
