I just noticed that LW is not integrating transparent items with the backdrop image, where the backdrop image is inserted from the Compositing tab. I can't believe I have never come across this before. FPrime does the job correctly; LW doesn't. Why and what can be done about this?
Alpharalpha isn't doing the trick with the complex object. [Interestingly enough it creates a whole bunch of vertigo spirals]. Will rendering out a sperate image and alpha pass to be composited in Aftereffects have to be the [long] way of getting this done?
