Doubles because realization. Aphtonites. You're saying those planets are DTS shapes, correct? That means you have managed to put actual textures (Not just single color) on them. Something that I have repeatedly failed to do. May I have one of the planets? It doesn't even need to be the actual planet model or the texture. I just want a model that has a proper texture mapped to it and that works in game so the texture shows.
I won't give you a planet, but however, I'll tell you something : UV mapping.
The each planet has three textures, the terrain texture wrapped around it, the "glow", and the inside atmosphere.
Also, I'm planning on hosting a public test for the map.
