Egon, I have a game that uses a sky sphere object that I wrote years ago. Now I want to convert it to the util.Skybox, because it's so much easier to deal the textures (not to mention easier to find stuff for). Problem is that this game requires me to collide with the sky. I could keep the sphere just for the collision bit, but I'd much rather be able to collide straight with the skybox (for one thing, it would save a good deal of polygons and for another it would be better for future games!). The best way to do this, I think, would be to get a method like Skybox.getObject3D(). Would you be willing to do that?
