Thank you!

Each blade of grass consists of 20x20x2=800 smooth-triangles.

As for now, the macro generates 25 (may be set to a different value)
unique blades, each with own bend, lengths and spans. Of those, for
each little bush/patch of grass, 20 are picked, scaled, rotated and
positioned.
In this manner, it is practically impossible for two blades in any
of all generated patches to be identical.
Using 5 patches with all different blades makes it almost impossible
to spot the same mesh in a scene, making it look much more realistic.
To answer your questions, the blades are internally generated only
as arrays of vertices, later on, the different blade-data are combined
into one patch. So blades aren't seperate, I want to make a
High-Res-blade-macro (with UV-Mapping and more surface-detail) for
close-ups, this is "just" a "filler". ;-)

Not yet, and I'm yet pondering if it is really needed for these
low-res blades...
