Actually I believe there are 6 or 7, but we get your point.
Oh I see, so far I could only find around 4-ish. It makes me a little sad because I strictly remember that in the older Sins games there were many more unique sky boxes, and a lot of those got taken out
My favorite part about the sky boxes was when they'd reflect off the ships and gave them a whole new depth
Sins of a Solar Empire is unfortunately not about nice things, as you can say from the number of planet types, and the planet textures. Only mods add depth in these fields. Ships and ETC are nice, but many things lack variety.
I've looked to mods, sadly all of them choose to change strategic things in the game instead of leaving it vanilla and being a simple texture pack. If anyone could recommend one that adds custom sky boxes/planets without changing the basic game mechanics that'd be awesome
Skyboxes (that don't look compressed to hell) are pretty large in terms of texture memory use. We'd rather spend that budget elsewhere.
I see. I guess I'm just more of a casual audience, I pretty much always play against the AI and am more focused on the beauty of the game. Oh well, different people enjoy different things.
