Hi,
how is this possible?

thanks.

One method I use is culling objects that overlap after scattering them. You can use the point's scale with pcopen to find overlaps. Its pretty quick. Careful that when comparing a point cloud with itself with pcopen, the closest point found will be itself. You could also use this method to push objects out instead of culling, since you could have the radius and relative pos of overlapping objects.

Another method (i haven't tried yet) is maybe using a grain solver to push objects apart based on their scale. Maybe not as fast and will require simulating.

So i tried the grain solver method for fun and it works really nicely.

you can as well do Point Relax SOP, which pushes points away from each other using their pscale with optional surface to slide on

The Houdini community's helpfulness never ceases to amaze me! Thanks Tomas and Nicolas.
