Is there a way of rendering geometry with camera's image plane, and still maintaining geometry's alpha in the render? I don't want to use geomety with BG technique.

Hi,

YOu have to know that rendering with an imagePlane will give a full alpha.
So set the opacity gain of your object's material to black hole, then in comp, invert the alpha.

Hope this helps
