Thanks for bringing up deep UV maps again Frank. I am so looking forward to being able to do true deep camera projection with just a deep opacity image and Nuke camera as the input!
I know some places have the tools, but as a workaround with some of the benefits, I've deep unpremulted the opacity out, flattened it then used a regular STMap node. This saves the need for an unfiltered data pass. Then I added the motion blur back in with VectorBlur, using the flattened deep opacity as my Zdepth source.
