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!
