I want to draw objects that are VERY large when scaled with respect to other objects such as drawing a space shuttle with the earth in the background.
Within the confines of the engine, what is the best way to draw the planet itself so that I can provide a good amount of detail? Should I just draw one gigantic sphere with the largest earth texture I can find, or is there a smarter way to approach this.
I think in this case, I’d use two cameras. There’s no way you can model actual size objects here, since your far clip plane would have to be ridiculously large, and you’d end up with floating point imprecision issues. See this 3D skybox topic for some ideas.

Thanks Eric, I will take a look into how I can implement that. I’ve been having a few issues with Unity since the tools are clearly not designed for the type of content I’m building.
Hmmm, that doesnt sound like unity at all. Things can be frustrating, granted, but pretty much anythings possible. I’ll keep an eye on your posts and help where I can.

Well, the tools are very open-ended, which means there’s very little they aren’t designed for. The downside is that there’s a bit of a learning curve since there’s so much in Unity. The upside is that it’s the most fun learning curve I’ve seen yet.

That is true, i cant think on something that cant be created in Unity (virtual reality talking…) but since its a game engine, you need to think as a game creator, knowing the limits of the hardware and the realtime rendering.
All converges to optimization, and creating world size object as a world size object is not optimum solution at all.
You can create whatever you want, but you will not create it as is supposed to, that is the key.
Ask in the forums any doubt, people here are very nice and willing to help!
