40•vicioussquid•5h ago
A liminal brush-based CSG editor and game engine with unified (forward) renderer inspired by Radiant and Worldcraft/Hammer

Compact and lightweight (target: Snapdragon 8CX, OpenGL 3.3)

Real-time lighting with stencil shadows without the need for pre-baked compilation

Looks awesome. Anything been made with this?

Other than the 14 examples included, not yet; this is brand new and I am reaching out to the community to create some stuff with it, extend it with angled brushes, new entity types, etc

Thanks so much for your interest.
