There appears to be an error in the "Quick Start" part of the grasstex
documentation. Try putting the pigments inside texture statements,
because official POV supports layered textures but not layered pigments.

object{Terrain
   texture{gt_ground()}
   texture{gt_grass()}
   texture{gt_flowers()}
}
