[Closed] matching the direction of light

Aug 23, 2009 5:20 am

Hi all
Here, I’m trying to match the target light’s direction to the source light yet, keep its length. I’m pretty new to max script and this is the best I could come up with so far.


sourceLit = $Direct01
targetLit = $Direct02

sourceDir = normalize sourceLit.pos

targetLit.pos = (sourceDir * (length targetLit.pos))

I was able to get that right direction when targetLit.target is positioned in [0,0,0] but
couldn’t figure out when the target is not in the center in world position.
It’ll be great if you could help me out with this

Thank you very much in advance.

With the assumption that you have two target direct lights and you want the second to point in the same direction as the first while maintaining the distance to it’s target. Does this do what you want?


   sourceLit = $Direct01
   targetLit = $Direct02
   
   targetLitTargetDistance = distance targetLit targetLit.target
   targetLit.target.pos = targetLit.pos + -sourceLit.dir * targetLitTargetDistance

Cheers,
