Re: [applekeynote] Rotating objects with drop shadows.

Thanks,
 
This "eclipse" approach would work if ancient coins were truly round.  Unfortunately, their outlines are highly irregular.  As an example, try this:
 
 
The black background works wonderfully with instant alpha.  I guess what I'm askung for is that the shadow be recalculated during the action.  It would certainly be processor-intensive.  But such and option should be available for export, where each frame of the build is calculated separately.

I have a build which moves, resizes and rotates obverse and reverse

solution for this?

Duplicate the image, move the duplicate behind the original, give the duplicate a drop shadow. Remove the drop shadow from the original, and rotate it - the duplicate will not move and will therefore keep the original light source shadow.
