I was thinking of perhaps pasting some text on a transparent polygon plane in Maya and then moving it past the camera. With a starfield in the bg of course. The only thing is I can't think how to make it fade out in the distance. Maybe the lighting will do that naturally or something. I dunno. I think Bioware should just tell us how they do this stuff. lol
For the Space scene I just putted in a JPEG image of space in the Enviroment Background.
I have no idea what its called in Maya, but in Max if you just render an object the default background is black.
In the Render Settings under Enviroment you can change this black to anything you want.
That is where I putted my starfield with the Planet.
Plus the starfield stays forever at an infinite distance, you can send your ship very far and deep the starts won't change.
A con ofcourse is, no matter how you turn the camera you'll keep seeing the same starfield.
But I found it worked good enough for an approach shot.
But if you want to go real crazy and do a 3D planet I've got this Tutorial.
Its still for Max but it might give you a good idea how to do it :)
