		+
		+	One thing that may not be clear to you is that we will know, in the texture, where poles and rails and catwalk intersect. We will know because of ambient occlusion baking. You'll be able to see the ambient shadowing the end of the poles produce on both sides of the catwalks and rails; so it will be possible, if we want to, to draw some kind of attachments. We could, on the catwalks, put orange bands that cross them wherever there are poles intersecting, which will give a huge feeling of consistency between geometry and texture, and between geometry and bumpmap. Something a lot of modellers and texturers tend to underestimate... Consistency is the most powerful virtue in modelling; and when geometry and texture are consistent, they become greater than the sum of the two.

+'''We're basically DONE with the seams! :D'''
 Before starting with the unwrap, though, there's something that's been bothering me all along: The catwalks are a half-assed job. Problem 1 is that there aren't enough posts to hold them or the handrails. I was trying to be miserly with the polys, but we got like 20k polys already and a few more is not going to suddenly kill the framerate. Problem 2 is that in the bottom catwalks, the vertical poles interpenetrate the hand-rails. Problem 3 is that there aren't enough lights, and the few I got there aren't properly adjusted, brightness-wise.
-And why are lights important? Lights are mightily important in large ships. They come for free first of all, as they are too local to bother OpenGL with them. Instead, the light they contribute is precomputed off-line (in Blender) and baked to the light map (AKA the "glow texture"). And this precomputation is of high quality, with local shadows and all, so they enrich the final look of the ship more than anything else, really; and here I was being lazy about it...

		+	The back of the square radar dish is already partly split, and anyhow, I'm thinking of just LSCMing it. The pole that holds it is an 8-sided tube, though, and needs a seam to unwrap cylindrically.

		+	The other poles are square, and the cube boxes are cubes :); and not all of it was split but I just did. However the cables are smooth-shaded square section (diamond section, if you prefer) and can use a seam along.
