@ALAN - Render help - Luminance Depth

Hi Alan,

I'm trying to render out a group of sequences but struggling with the luminance depth DOF pass. The beauty pass has rendered  and I've set up a Luminance render layer and adjusted the settings. When I render in maya I get the results I want (example pictures below).

However, when I batch render the sequence I only get black screenshots?

What am I doing wrong?

Thanks

Paul
