VRayFastSSS2 make it transparent in some areas

[XavBo]

I have a ball and I want to animate a ramp that should build a transparent circle.
Somehow there is no way to make a transparent the VRayFastSSS2

The circle that is now brown needs to be transparent i can see the red circle behind.
Those anyone know how to solve this issue?

I already tried to use the blend material, but the base color does not have a slot for transparency as the other added slots of materials.
The texture layer does not work either.
I tried also to connect my VRayFastSSS2 into the diffuse of a new vray material and nothing will transparent.

So, how does the VRayFastSSS2 can be transparent in the desired areas (in my case in a circle form using a ramp)?

BTW. the green skin is also terrible! And this color is coming form the "MAYA texture layer" Yes I also used the maya texture layer to do some test.




EDIT:
BTW I'm using this as a skin shader so mein VRayFastSSS2 ist set as:
Color Mode = Sub-surface color and scatter radius.
with:
Single Scatter = Single

Why the VRayFastSSS2 does not have any slot for transparency !
It is a material and nees to be also manipulate in all forms .

Could use a blend material and animate the blend use your sss as a base and your trans material in the 2nd slot.

Hi stezza !
I found a way, but only works if you plug a MaYa node .

IT IS WEIRD !
I hope the great CHAOS Team can come to me about this issue, because this is not acceptable IMHO !

Currently, blending the VRayFastSSS2 with a fully transparent shader (white refraction, IOR 1) is the way to go. Make sure the Base Material is the VRayFastSSS2. I'll talk to the product owner to consider adding an Opacity slot in the shader to avoid the hassle.

EDIT: Logged an improvement request (internal bug-tracker id: VMAYA-13302) to add an opacity slot to the VRayFastSSS2.

AWESOME !
Thank you soooo much!

I mean... I found the way to do that, but was not that easy to understand what happened.
