Did a few experiments with the LW 4.0 Shadow Alpha feature...
Found that the instructions in the manual and the addendum don't
work... i.e.: when you set the surfaces to black (Diffuse setting at
0%) no shadows are generated in the alpha channel image.
One way I've found to get it to work is to set Diffuse to 0.1%.
You can also set the object dissolve to 99.9%, but then the
"stand-in" objects won't cast shadows themselves (ray-traced variety,
that is).
Is there a better way to do this?
REALLY neat feature, tho. A great alternative to trying to balance
the luminosity and diffuse settings on a front-projection map.
