Quote - Dunno, BB.  Maybe I'm misunderstanding this or wording it poorly.  This is what the Terradome user manual says:

"Another great feature of the TERRADOME lighting system is that the sunlight is parented to
the skydome. What this means is that as you rotate the skydome throughout 360 degrees the
sunlight rotates with it projecting from the correct place in the scene and casting
corresponding shadows."

And it works great, I've done it and indeed the shadows fall very differently as if the sun is moving. Great feature for animations.

Due to the childish TOS changes, I'm not allowed to link to my other products outside of Rendo anymore :(

Food for thought.....
