Diameter range
In the sphere generator, Diameter is about 3–200. Layers and totals grow quickly with size. In Survival, validate centering, scaffolding, and supply routes on a small diameter (e.g. 10–20) before scaling up.
This tool outputs geometric slices — it is not photo quantization, so “max colors” style controls do not apply here.
Hollow vs solid
Choose Hollow or Solid. Hollow shells save interior blocks for domes and walkable orbs; solid suits filled decor. Re-check total and per-layer counts after switching.
Failure modes: stocking for hollow then building solid (short materials), or finishing a solid orb when you needed usable interior space. Decide the use case first.
Layers and counts
Use Layer with Previous layer / Next layer. Per-layer and total block counts help staging. Titles look like “Sphere {d} · layer {z} of {d}”. Pick one build order (bottom-up or equator-out) and keep a center mark so layers do not drift.
