It would be really good for something I am working on if I could combine some separate particle ops I have setup with different sizes and shapes using metaball Copy sops so that if I combine each Copy Sop network, they will inturn blend globally together. I can kind of achieve it with a lot of fiddling around by using convert and skin SOPs but it isn't very effecient. I was wondering if anyone has ever found a more procedural method of doing this kind of thing so that you could get separate metaball particle networks to combine with each other.
