Help, Shadow Catcher problem in transparency

[danielmuresan]

Hi.

 

My name is Daniel. I have a problem with v-ray shadow catcher. I've created the scene with a car and i want the shadows from under it. So i created the plane for catching the shadows, I've tried the v-ray properties method and vray wrapping mtl method and none of them work for my problem. I will attach the printscreen so you can see what i mean exactly.

 

The problem is that the shadow caught by the plane is not fully transparent as i want it, it is created from black color to white color, so it looks very nice on a white background, but when i put the model on a black background as shown in attachment you can see that it is pretty white, and is not constructed like in photoshop from black center to transparent layout, ass i explained in those photos with black gradient dot that has a center constructed from black and margins from the background. I want my shadows to be black but to extend to a transparent background, and the gradient got from background itself... i hope that i explained the problem pretty well... even if you need more input about the problem just write it down here.
