Hey Battuta, I bet combining threads would be a good idea, so let's go ahead and do that. I'll edit first post on them so all ships are available and no posthunting ensues.
ShadowGorrath, the triangles are a sneaky way to get PCS2 to size the bounding box appropriately. As you can see, detail0 has no geometry that extends beyond the main weapons. This causes the bounding box to be to small, and collision detection works on half the barrels. Those triangles make the bounding box large enough to accomodate all turret weapons, and are set invisible no collide so they won't randomly whack fighters around.
Woah monsieur Zane, how did you ever get a hold of those normal maps? Those are from the alpha version, and have been replaced.
