I'm curious about something, how are you managing the scenes where a PM contacts you through the force/comlink inside the Ebon Hawk but the EH is obviously using the textures from said module you're currently in.
You'd have to be specific with when this happens, as the most recent part of the game I have played is the last part of the game commencing with the Telos station attack.
It depends upon the models they are using, typically when it cuts to some other part of a place, it doesn't use that place as you would see it as the player moving through the environment. It's actually a fake enclosed set that is in the same level "scene." So it you are on Telos, and it cuts to the "Ebon Hawk" it doesn't load the Ebon Hawk level and models it just jumps to a small little enclosed interior model that is way off to one part of the level.
Anyway, depends upon the model in that you could replace the textures with ones that look a better fit, and if that doesn't work or isn't an option, you can replace the models used themselves.
However, I have yet to do any of that so far; my focus has been on other things and it has been so long since I played various parts of the game, that I am just unaware of them. Also, I can't help but end up playing a dark-side character, so conceivably, there are parts of the game I have actually NOT seen as they are restricted to light-side players.
