- After some more experimentation, I stumbled upon THE SOLUTION:
-
- Need to turn on the "FG Fader Alpha" button in the "Image
- Compositing Panel." Otherwise, any non-black shadow-alpha
- surface is NOT blocked out by the alpha image.
-
- With that button on, it IS possible to control precisely the color
- and density of the shadows by adjusting the surface color and
- diffuse settings for the surface, making it easy to match the shadows
- in the BG image.
-
- YES!!! Whoop, whoop, whoop...!
- (My enthusiasm is tempered slightly by the realization that this bit
- of info could, possibly, be in the manual somewhere... :*)
-
- Regardless, it should be mentioned in the explanation on how to use
- the shadow-alpha feature, me thinks.
