Hi, When I rendered a scene with a background of Matte objects, the alpha channel is white where my "target" object is (correct) and a solid medium grey where the matte objects are.(?) I had expected the matte objects to show through to full transparency. Anybody have any experience with this? TIA, – Ron

>>and a solid medium grey where the matte objects are.(?) Are you rendering with fog? That will tend to mess up matte object alphas.
