    Interesting. I'll have to test it some more, but if you got it to work, then I'm sure you're right. I'll give it another go.

    Hi ledisnomad,

    are you sure LightDirection does not work with your light? I just performed a small test and was able to get/set Location and Direction of a directional light...

    I'm modifying the "RotateObjectsToCamera-Add" script that is on this forum to work for my purposes. I've gotten that to work so that it copies a surface or mesh plane to a bunch of points, then rotates them to face the active camera. All good.

    Now I would like to add to it to repeat itself, but this time copy the same objects to the same points and face my sun, which is a directional light. All this so I can have billboard trees and people that cast shadows correctly.

    So to my question: is there a way to get the direction of a directional light? I've looked into LightDirection(strObject), but it seems to only works for finding the direction of spot lights that have a location and a target. Any thoughts? My only thought right now is that I position the directional light so that it points at the origin, but that isn't a very satisfactory solution.


Why are these buttons gray?
