A little planet

Build a planet on one sphere: hills, seas, and biomes.

1. Start from a sphere

Make a new fig. Under Detail, select Balanced for the size . Then place one Sphere with Size 20 in the middle of the grid. The largest Size (24) reaches the edge of the workspace, and the hills have no room to grow there. The planet is one piece.

2. Raise the hills

In Build, select a few small patches around the sphere and press Pull out once or twice on each. Keep the hills low and wide so the seas have room. Each face grows the way it points, so the hills point outward from the planet. The bottom of the sphere rests on the floor: a patch there shows No room: you’re at the edge of the world, so raise the hills on the top half and the sides.

3. Carve the seas

Select the regions between the hills and press Push in once, with the Floor row on Scoop so the sea floors keep the sphere’s curve. One step down is enough. Scoop needs faces on the same level, and on a sphere that means one or two faces at a time: with more, the status line reads In needs faces on the same level: tap fewer at once.

4. Paint biomes

In Color, tap faces, tap a swatch, then press Fill. Fill the basins blue, the lowlands green, and the hilltops pale stone, patch by patch. Open Paint on a green patch and dot in a few darker pixels for trees.

5. Export the .glb

Export the .glb , and make a rotating Loop in The Camera . The fig above is this planet: orbit it, or download the .glb.
