I see what it was - I used a default camera ie NO camera, and if you do that
there are no motion vectors but you do get RGBA
However you do get them once a camera is placed there (same position).
You also get a different depth result, point and normals. That is with your
script and the camera off or not attached you just get the geo, not the
particles
Dont know if that is a bug or not
