 Todays RenderMan question:  How's does one get shadows?? And why
isn't automatic? (i.e. You have a wall, you put a spotlight behind
the wall, why isn't there a shadow??

>From reading portions of the RenderMan Companion, it seems that
you have to create a shadow map first and then render the scene
again and use the shadow map to get the shadows.

I tried the following in my RIB file:

Display "test.z" "file" "rgbz"

This seems to create the shadow map file (I assume). But then I can't
load in the shadow map file in the second pass. I've tried stuff like:

Declare "shadowname" "string"
MakeShadow "test.z" "myShadow"
LightSource "shadowspot" 5 "shadowname" "myShadow" "from" [0 0 0]
	"to" [0 1 0]

 Any thoughts?

Mike

ps. You get bonus points if you can identify what musical group wrote
the song in the subject field..  :-)
