I am really allergic to Blender, i think to remember that there is an easier way to export the textures all in one, rather than doing one by one (must retrieve how to do it).
Did you notice the original model carries Kara "Starbuck" Thrace's Viper escorting the mothership?
Yes, i removed them because i wanted to focus only on the mother ship.
I had to triangulate the model to avoid artefacts in OR, they are hard to detect without a close inspection of the individual meshes.
So far, with the version i have, AO is the only way to produce nice shadowing effects.
I prefer my own set of textures, especially the GALACTICA text logo, however i shall use the landing strip emit to enhance mine.
I have attached a "pacifica" version that was downloaded from Foundation3D that you can't access yourself.
