What do you mean lights dont change when you move their transformgroup? Pointlights certainly do, I'm not sure about other types.

I put a point light in the center of the sphere. I want to move the sphere/pointlight (a glowing orb) around in the scene. Since light positions don't change when a transformgroup's transform (location) is changed, how do I keep the light within the sphere as the sphere is moved? The sphere is attached to a sequence of transformgroups. For example: TG_Rotate(orbit)->TG_Translate->TG_Spin->TG_Scale->Sphere Seems like I need to have some event such that whenever *any* of the multiple transformgroups change their transforms that an event handler is called to change the location of the pointlight. Is that how you do it? Does anyone have an example of coding this? Is there another way I can do this? (Would love to simply attach the pointlight to the TG_Scale in the above example, but that doesn't work.)
