Hey guys, I'm trying to make something like this:

I succeeded in making the outside of it, by cloning a bunch of mini-spheres set to object mode (vertex mode, referencing a bigger sphere. adding a displacer for some randomization), putting them inside either metaball or volume, and that works well:

But of course this way it only shows the outside but I want to have a transparent effect going on to show a volume of minispheres bundled together.

So I thought that a dynamic simulation to pack them together would be a good idea (so that I don't have intersecting geometry) but that is a little too taxing of a process and I think not possible with the hardware I have.

Could you suggest what may be the most suitable approach to this?

Thanks!
