Matte Shadow material Vray problem

 

How can Extract the shadow information on a separate channel???

The answer is matte shadow material. BUT althrough the scanline renderer works fine, the Vray renderer does NOT the job properlly.

 


1. a simple box, plane and spot light (for cast shadows) scene in max

 

2. Max scanline render with standard material for plane

 

3. Scanline render with matte/shadow material for the plane

 

4. The alpha mask for the image (scanline render)

 

5. The alpha mask for the image rendered with vray


Vray consider also the plane as a object and do not treat corectlly the matte shadow material applied.
download the scene (right click - save target as..) matteshadow.max
