Ship's UV layout fixed

I divided it into 4 parts: white, gray, black and red.

White is more like (white)painted metal for the outer plates..

gray is just metal, black is more of a heat-resistant? metal

I don't know how each part of a plane/ship is made of, so I just call all of them metal lol

Red is not UV'ed, it's just shaded in red and I'll apply material ID on it when I render

so I can make them glow when I composite...

(this had the most polygons; also I had to scale up some parts because I'm gonna have detailed textures on those parts. then I tried packing them up...and oh god.....)

(this one doesn't have to packed that tightly anyways, but I did pack them tight, scaled them and arranged

some of them so it doesn't look too messy around the main meshes)

Separate UV layouts for 3 different materials.

it took hours to pack all of these tightly in space (so I can scale them larger

and use more space....I'M NOT USING 8K TEXTURES, 

it's too big....I'd rather spend time packing these UV's and scaling them up

so I can use more UV space....instead of wasting all that space

and ending up with twice the render time)

4K texture! yea!
