// planet spheres are more or less the same as the engine generated ones, but with 3 different highly customized uv's that makes the planet tiling+parallaxing possible.
// the vertex paint channels got a bunch of polar gradients that more or less goes like this:
// red: clamp(abs(uv.y * 2.0 -1.0) * 3.0 - 1.0, 0.0, 1.0)
// green: abs(uv.y * 2.0 - 1.0)
// blue: max(0.0, abs(uv.y * 2.0 - 1.0) * 4.0 - 3.0)

// Ico spheres got a very even vert distribution, making them very useful for running detailed per vertex instructions.
// lod0 is 20.480 tris, lod4 is 80 tris.
// Each lod comes with a simple spherical uv, with pretty poor seaming, since the geometry is not uv friendly.
// In the vertex color channel is a polar gradient for blending origo xz/atan() based projections.
// uv2 and uv3 is unused
