[Sidefx-houdini-list] randomly clumping values problem

Thanks Jesse, I tried the random_sobol function - I assume that works well when the offset (say ptnum) is distributed well? But it seems difficult to get a good distribution in 2D space... I can imagine it working well when the objects are in a line. Unless I'm missing something?

Check out the Sobol random function.
