How to get the VRayALSurfaceMtl shader in Render Element

V-Ray V-Ray for 3ds Max General

Hello,

I would like to know how to get the VRayALSurfaceMtl shader in the Render Element?
Because it appears all black in the VrayGlobalillumination and VrayRawLighting render element

Thanks for your answers

Without mixing in the SSS, the ALSurface works fine with the lighting/GI RE.
Once SSS is mixed in (mix of 1.0), the shader will appear in the SSS RE.
For Mix values between 0 and 1, it will appear in both Lighting/GI and SSS, proportionally to the amount of SSS mixed in.
