Minecraft star generator

Number of points plus outer and inner radius and the block star is ready: a five-pointed star on a plaza, an eight-point floor mosaic, a sixteen-point compass rose. Outline or filled, in 3D at once, export to .litematic and .schem.

How it works

1. Set the dimensions with the sliders — the shape is recalculated instantly and shown in 3D.
2. Pick a block (some tools take two: main and secondary).
3. Turn on Layers to see the shape slice by slice — handy for building by hand.
4. Download .litematic for Litematica or .schem for WorldEdit.

Examples

• Five-pointed
• Eight-point mosaic
• Compass rose

FAQ

How do I make the points sharper or blunter?

Sharpness is the ratio of the radii: a small inner radius with a large outer one gives thin sharp points, close radii give almost a polygon.

How do I build this without mods?

Open the schematic in the viewer, turn on Layers and place blocks layer by layer on the grid. With Litematica or WorldEdit the schematic is pasted in one go.

Why does the shape look stepped?

Blocks are whole, so every curve turns into steps — the game does the same. An odd size gives a clean centre block, an even size gives two.

Is it free, no sign-up?

Yes. Everything is computed in the browser; the file is built locally and never uploaded.
