Reflect alpha doesn't work with vray 3.00.07

[eyepiz]

Basically I'm trying to separate Shadows from reflection as described in the Tutorial bellow. I'm trying to use the VRayExtraTex for the reflection alpha to be separate from the main alpha...so far no luck.

Hi,

Since the V-Ray Wrapper has the ability to catch the reflections, the alpha channel contains information for both, shadows and reflections.
If you need to use them separately, the render should be on 2 passes (second region render for the matte surface only).
*) one with disabled reflection for the material used with V-Ray Wrapper shader to get only shadows
*) second with reflective material and ExtraTex (with Dirt map) render element to get the reflections

Actually there is another approach for this, here is example screenshot of the result and option that i have used:

Just my 2 cents,

I ran into the issue today, and just lost 2h because I couldn't find out why it wasn't working.
I hope this will be fixed soon, please let us know when this is working again.

Cheers

I think it's fixed in the nightly builds already; I have to check the stable ones.
