License: the short version
Commercial use allowed, even on this free pack. Drop these sprites into games, videos, streams, PDFs, websites, prototypes, VTT mockups, and campaign graphics. No attribution required.
The one thing not allowed is redistributing the sprites as standalone assets. Full terms in LICENSE.txt inside the download.

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 etched numeral geometry. All artwork is procedurally generated in Blender Cycles from Python/bmesh; no generative-AI models were used.
