I cannot seem to figure out how to save the Z-buffer in a separate file…
I rendered the scene, and attached a file output node to the Z of the RenderLayer node.
I want the Z-buffer in 32 bit, so I set the format to RAW targa (I cannot read OpenEXR with my external application).
I created an extra ‘check node’ with a normalise and a viewer node, which outputs fine (shows me a recognisable depth map), although I don’t want to normalise the 32 bit z-buffer I’m saving of course!
However, the raw tga file is completely white (in the hex editor it shows only ff’s)! Any idea what I’m doing wrong?
