 Hi, I'm not sure what the above error actually means, but I think
yes, you should specify 4 spheres for a cubic_spline, and 4 lines of
parameters, here's a golden worm-like thingy:

sphere_sweep {
   cubic_spline
    4,

    <-3, 4, -3>, .03
    <-5, 0, 0>, 0
    <-1, 0, 0>, .3
    <-2, 5, 0>, 2

    translate <2.5, 1, 0>
    scale 3
    texture {T_Gold_2A}}
