Hmm well that's the usual meaning of baking textures (at least in C4D). The
point is to turn a complex, computer-intensive procedural texture into a
fast-rendering bitmap. A typical use for instance is to bake procedural
dirt.

For spheres it's almost straightforward : render a sky_sphere using the
pigment and a spherical camera in the center. The resulting map can then be
used on a sphere as an image map identical to the pigment, at the price of
some rotation and mirroring. For other primitives it's surely tougher and
probably requires a lot of maths...
