Ra Engine

Digiflux.one is a Vulkan 1.4 hardware ray-tracing graphics pipeline built for real RTX-class GPUs — theatrical-quality global illumination, physically correct lighting, and no rasterization fallbacks pretending to be RT. Reflections, refractions, and GI share one coherent ray budget. Emissive light actually bleeds. Materials speak GLTF 2.0 (including KHR lights and transmission).

Ra Engine is the editor and toolchain on top of that pipeline: terminal-first TUI + live render view, scene hierarchy, fly mode, light placement, and GLTF export — so you can build and iterate levels without renting a seat forever. Buy once at $49.99 per seat. Perpetual license, updates included at your purchase price, no subscription and no per-install runtime fee.

Revenue share stays simple and public: 0% under $100K/year, 2% on annual revenue above $100K, 1% above $1M, thresholds reset each January. Terms for your seat don’t change later. Hardware baseline: RTX 2060-class (RX 6600 / Arc A380 in scope) with VK_KHR_ray_tracing_pipeline required.
