Hi, i am new here. Thanks for your time, i have this problem. I have been rendering in 3dsmax 10 using vray and when i want to make a scene in a 2d photograph, some of the materials seem to be translucent as they let some blury part of the photo into the material. For example, in this scene the column that holds the structure shows the part of the windows that should be behind it. Can i get some help please !!! Thanks in advance. (image attached).

Ps. I used vray matte/shadow for the volumes of the house(photo) to catch the shadows.
