Right now I am just practicing some basics with matchmoving and tracking live footage (with Boujou or PFTrack, etc), bringing the scene into Maya, and then putting simple things onto it such as text or shapes. I have a plane acting as a shadow catcher so it has a "Use Background" material.

When I do a test render of a frame within Maya, everything works out. The plane is transparent but allows the shadows from my objects to be cast.

When I batch render though, the area of the plane becomes visible though.





Any thoughts what's going on? Thanks!
