I am rendering TGA images with Z-Depth in Maya. The Z-depth channel is not attached to TGA image files; they are output as a separate file. How can I use Depth Blur in Maya Fusion when the Z-depth channel is separate. Is there a way to tell Fusion which files to use for Z-depth? Or is there a way to combine the Z-depth channel with the color and alpha channels creating an image file that contains all three channels?
