I've been rendering single frames, using render layers, and added a luminance depth preset shader from a specific camera. In the Primary Framebuffer of Render Globals I used the RGBA datatype. Under the the camera preset I have the output settings as "renderable, image, depth, and mask".

But after all of these settings are set and I try to render more than one frame using the batch render all I get are images with an embedded white alpha, no true alpha for the object.

Anyone know how to render a true alpha channel in batch mode for an z-depth image with out resorting to using a seperate render layer and a preset geometry matte shader to create the alpha?

Thanks :)

Are you using MR shaders? Try ticking the "Pass Custom Alpha" box in the globals.
