for 3ds max 3.x/4.x
Using geospheres it creates fractal looking object. Just check examples below and everything will become clear. I don't recomed seting level to value higher than 5 on slower machines. I've had an oportunity to test this script on dual PIII 1GHz and it took few minutes to create complete mesh of level 6. Large arrays are simply too much for MAX Script to handle. I've also added spinners for segments in first and last level. Smaller spheres at last levels don't need as much segments as first biggest sphere. Segments value for rest of levels will be interpolated.
