Wow, lots of replies...

@Zacam and Galemp: thanks and thanks again for the nameplate help. I'll start working on it at some point. And I think I know where to put it.
@Snail and FoxTango: The model will be re-converted anyways, so I still might change the engines a bit, but I suggest you wait and see them textured first.
@Galemp (again

): The textures are not finished yet.
Firstly, as you will see if you check my post with all the images, I toned 'up' the normal maps to make sure the new 'smaller-panel-lines' would be visible. They are on a separate layer on the heightmap .psd, and they will be heavily toned down on the final version
Secondly, the back 'panel' of the engines (the part where the thrusters actually stick out of) has NOT been textured. No diffuse, no normal, no shine, nothing. So, of course it looks like $**t. And the yellow glows are still WIP. They are going to extend to the top and bottom of the Hercules-like engines (possibly -I might not do this, as it is not alike the retail Zephy) and to the rear 'thruster' panel (this I will definitely do).
I think I answered everybody.

Oh, and about the three textures: It's possible to bake the Orion one onto the 'base' diffuse one, but there's a small voice in the back of my mind advising caution. If I do it, it will be the absolutely
last thing I do
