Runebit Dice: Black Opal (Complete Polyhedral Result Sprite Pack)

The Black Opal Polyhedral pack is live.

Seventy photoreal result sprites covering every face of D4, D6, D8, D10, D% (percentile), D12, and D20. Three sizes per sprite (1024, 512, 256 px), transparent PNG, commercial use, no attribution required. Drop straight into game UIs, Foundry, Roll20, any VTT, stream overlays, rulebook PDFs, or wherever you need a die-face graphic.

How it was made

Every sprite is path-traced in Blender Cycles from procedurally generated 3D geometry. The numerals are recessed mesh cavities (booleaned into the die body) with a white inset-etch material; the body is a near-black opal shell with a physical thin-film iridescence layer. The iridescence is driven by a view-angle interference calculation so the hue shift is physically accurate rather than a texture overlay; the colors you see depend on where the camera is relative to each face. No bump maps, no decals, no AI in the pipeline.

The whole dice pipeline is Python plus bmesh, so new themes and shapes can be added on demand and stay perfectly consistent across packs.

What's coming

• Free Black Opal D20 sample is already live at runebitdice.itch.io/black-opal-d20. The twenty D20 sprites in this polyhedral pack are byte-identical to the freebie ones, so they composite cleanly side by side.
• If you want to try a different palette, the Nightfall Marble Polyhedral pack, Opal Moonstone Polyhedral pack, Amethyst Crystal Polyhedral pack, Frost Crystal Polyhedral pack, Ember Runes Polyhedral pack, and Witchfire Plasma Polyhedral pack are all live in the same pipeline.

If you need custom dice visuals instead of an off-the-shelf pack, see the sample packet and request a scope at runebitdice.com. I handle bespoke renders, transparent PNGs, face-layout sheets, and quote-prep notes for crowdfunding and board-game projects.

If you grab the pack and use it in a project, I'd love to see it. Reach me at hello@runebitdice.com.
