Engine and tools

Inner Datum
- T-Engine4 and Tales of Maj’Eyal (GPL). Inner Datum’s code began as a partial port of the T-Engine4 roguelike engine, so it’s published under the GPL 3.0 or later. Copyright Nicolas Casalini and contributors.
- Inner Datum’s art and writing are our own work, as is its setting, and the GPL doesn’t cover them.
Art and models
- Meshy, an AI tool. We used it to make some of the rock and landmark models in Outer Index 3D, and we picked the ones we kept by hand. The Outer Index 3D page says so at the bottom, and so do the captions on those pictures in the gallery and the workshop.
