Or you could use Lightwave's Jitter... ;) Set the distance to a percentage of your objects size, then try the different modes, uniform, gausian, normal mode gives a nice effect, especially in subpatch mode. You can also use smooth afterwards, to smooth out if the mesh gets too jaggy. Try a stength of 1 and an iteration of 4 or higher, just try different iterations, I've used values up to 200 with some objects. Regards- Lemurtek
