NebulaKit
NebulaKit builds procedural volumetric tools for Blender. Everything here is deterministic maths rather than a stored asset: no image models, no downloaded textures, no external dependencies. Same seed in, same result out, every time — and the seed ships with the result, so anything you make is reproducible. The colour is derived rather than painted. Star colour comes from Planck's blackbody law at real stellar temperatures; gas emits in the actual nebular lines; dust follows Beer-Lambert extinction. When something in our tools is a convention rather than physics, we say so on the product page. Every tool ships with a headless test suite that runs against the file you actually download, on current Blender.
