Runebit Dice: Cathedral Window D20 (Free Sample)

Free, commercial-use, drop-in. Twenty photoreal D20 result sprites built as miniature cathedral windows: translucent amethyst-glass panels framed by raised lead came, soldered at every vertex, with citron-yellow vitreous-paint numerals. One sprite per face, every face from 1 to 20.

Want the full polyhedral set?

The matching Cathedral Window polyhedral set drops tomorrow with the full rose-window palette: every die in its own complementary color. In the meantime, other photoreal polyhedral packs from the same pipeline are already live:

Already grabbed the Emerald Crystal D20, Arcane Runes D20, or any of the other free D20 samples? All themes share the same render pipeline, so they composite cleanly side by side in a VTT scene or stream overlay.

About Runebit Dice

One-person studio. Every pixel path-traced in Blender Cycles from procedurally generated 3D geometry. No generative-AI imagery, no traced photos. The underlying scenes are regenerated from code, which is why new themes and shapes can be added on demand and stay perfectly consistent across packs.

If you need custom dice visuals for your Kickstarter, BackerKit, itch page, or board game, the same pipeline can produce bespoke renders, transparent PNGs, face-layout sheets, and quote-prep notes.

Credits. Numeral font: Barlow Bold by Jeremy Tribby (SIL OFL 1.1). Font is not redistributed in this pack. It is used only to generate the painted numeral geometry. All artwork is procedurally generated in Blender Cycles from Python/bmesh; no generative-AI models were used.
