I've used height fields to create cracks, as well. I used the "Lightning
Include File" from Jeffrey Brickley at
http://www.geocities.com/SiliconValley/Pines/3210/lightnin.html to make the
height field (set the lightning pigment to White and finish to ambient 1, so
you'll get a black and white picture).

Regards,
Dave
