How To? Mirror and horizont

Hi,

i’m searching for solutions or tips for 2 things.

First is reflection in 3D-Space. I’ve seen a few examples of reflection in 3D Space:

Some time ago, i did reflection with a „ReflectionMovieClip“, but aftern seen the examples i asked me, if there is a better way, than using a MovieMaterial with reflection in it. In the cubejunky game, there are reflections of whole cubes. How to doe that?

Second question ist, how to do a horizon. In the following example, sombody „fakes“ the horizon by moving a gradient, if the camera moves. But that would not work, if the camera should rotate left or right. Is there a way to do that? It should even look like in the example, with the smooth border between ground and sky.
