Correction to my last message. If you make an object a matte object because it comes between the object you want to re-render then you would NOT need to change the material – just changing the object's attributes to MATTE will suffice. The matte will appear as a black hole in the 24-bit image and the 8-bit alpha image whatever kind of material is assigned and be invisible when compositing. Mattes seem much faster than regular materials since no shading, texturing etc is involved. You still can NOT use them for objects with opacity maps, though.
