I initially figured that I’d need to rework my scaling algorithm for the metaballs approach because metaballs are just points in space whose boundaries are determined by a thresholded distance falloff formula; and therefore, my metaballs wouldn’t have a scale unless I set one. But… Since I’ll be able to scale a metaball’s transform object without affecting its radius, that means I can just link its radius value to its transform scale!
Here’s proof, courtesy of this demo:
