#Shadows
4 messages in this thread
I've been dreading asking this question for half a day now.
I've got a black tire which will roll thru a scene which is a perspective
matched
background. I want the tire to cast a shadow onto the background (give the
appearance of actually).
I've got a floor plane for the tire shadow to cast onto and can get just fine
shadows on it but how can I key out the tire and its shadow to composite over
my background.
I know I'm missing something painfully obviouos here and will be red in the
face when I see it, but I'm totally clueless today.
Why can't a matte object receive shadows if we want it to……
That'd be cool hu hu hu hu.
Erik,
use a pure blue (or any unnatural colour) material with maybe 25% self
illumination for the ground plane. Make the spotlight pure white 3x multiplier.
Turn off dither 24-bit before rendering. That should make sure you get a
consistent pure blue to key out and retain the shadow for composition in Video
Post.
For a more complete discussion and elaborate tutorial of this technique get a
hold of NRP's "3d Studio: Special Effects" – should be worth it's weight in
Pentium CPU's <g>.
Oh, and BTW dude, I was a co-author and originator of that chapter …. cool hu
hu hu hu hu <g>.
Martin, I went to my neighborhood Barnes and Noble yesterday to pick up a copy
of "3D Studio: Special Effects" and they don't have it yet:(…what a
disappointment, I've been looking forward to sinking my teeth! What's the
deal?
Regards, Connie

Beat's me! I have nothing to do with that end of the business. You can put an
order in for it though, and get it when the first copies ship. The ISBN is
1-56205-303-5. I suggest you contact New Riders Publishing directly to ensure a
copy.
