You really should try ABX's suggestion using functions. The way you use
(with eval_pigment) bears much overhead for what you want. You only need the
pattern and you can get that by using a function.
I like your idea and hope you'll get somewhere. However, I fear it's quite
memory intensive to have all the blades of a grass plane as extra shapes
(without copying patches), I hope, I'm wrong.
