After a while of not exporting transparent images, I have forgotten how I originally did this correctly. I have tried Render Write Nodes with no color card using PSD4, TGA4, and PNG4 file types and all export with a white background and no image visible. I am going into the Write box in the Node View and changing the settings there so I know that is not the issue. Does any one know how this actually works?
Was created back in the Animate days but still relevant.
