i would appreciate it if someone could offer some solution as to how to get a cube that is double the dimensions
3ds max -> Scale Tool & cut in nice big docking hole thing for the sphere...
+ New textures... higher res the better in this case [imo, since the cube is huge, low res textures will look like sh!t in-game...]
+ Obviously a new hard point.
Essentially, learn to model, texture, script... pretty much learn to mod. Most modders are busy with their own projects and real life 95% of the time when requests like these are made [some people get insanely lucky...]
Unless there's already a cube of that colossal scale available, but I doubt it...
Also, isn't there some problem regarding flying ships of that size? I seem to recall something having been said about that at some point...
at any rate, if you want to learn to mod the game you're in the right place. If not, you'll just have to be really patient until somebody actually makes that cube variant accurately... assuming anyone ever does.
