Hi.
What I'm trying to do is to create a simple horizon, as seen in old flightsim games. In fact just a monocolored blue sky and a green earth. I'd like to realize this by a second world called "horizonworld". That world actually contains TWO domes, one for the sky, and the other one for earth. I tried to modify the "AdvancedExample" at the jpct tutorial page, but I didn't succeed.
Can you please help me, or make a suggestion for a different/simpler approach? Thanks.
