Here's a little patch I've been working on. It is very similar to the 
crackle pattern, but rather than using a 3D grid of points that is 
randomly jittered, it uses a user-specified set of points. It is 
actually very fast, usually faster than the crackle pattern. It stores 
the points in a binary space partition tree, which it can then search 
very quickly, while the crackle pattern must always check a large number 
of points, and sometimes recompute all of them. The options available 
are the same as for the crackle pattern, with the addition of the 
points. You can specify the points alone, or with a blend map index for 
each point, giving you an effect similar to the "solid" feature, but 
with much more control.
