Nullcore is a small independent studio building tools for the VRChat ecosystem. We make the software we wished existed — fast, polished, and respectful of the people who use it.

Our first product, NullFit, came from a simple frustration: fitting clothing to a different avatar in Blender is slow, finicky work — and for people who never learned Blender, it’s impossible. NullFit turns that into a few sliders. Creators save hours; everyone else gets to make the outfits they bought actually fit, without touching a mesh.

We believe in tools you own, not services you rent. NullFit is a one-time purchase that runs on your machine — your meshes never leave your computer. No subscriptions, no telemetry harvesting, no selling your data.
