[Sidefx-houdini-list] Compositing -> Deep Raster -> Targa

Well I've been playing around with the Tiff's and I'm still having
problems. First I changed the renders to Tiffs, and the data types to
Float. However this was giving me blank results on the zDepth, so I
then changed the variable from Pz to just P, thinking that I could
then extract that data from the Blue channel of the tiff, but it still
seems to be clipping the data. Any other ideas??  Any help would be
great thanks.
