One tool, two kinds of people
A Blender add-on paired with the Nullcore Companion. It does the fiddly avatar work for you.
For creators
Refit garments to a new avatar, transfer weights, fine-tune the fit, and repair clipping in a fraction of the time. The tedious parts of a commission — handled — so your hours go to the parts that matter.
For everyone else
Bought an outfit that doesn’t fit your avatar? NullFit conforms it to your body with sliders — no Blender knowledge, no weight painting. The stuff that used to need a creator, you do yourself.
What it does
Fit-sculpt the garment
Fine-tune how an outfit sits — reshape the clothing to the body with sliders, no manual mesh editing.
One-click clothing refit
Move an outfit onto a different avatar and let NullFit conform it — weights, shape, and fit carried over for you.
Live preview + clipping heatmap
See the fit update in the viewport in real time, with a heatmap that shows exactly where the clothing clips the body.
Clipping repair
Find and smooth the spots where an outfit pokes through the body — without hand-editing every vertex.
Updates itself
The Companion tells you when a new version ships and updates in-app. The plugin stays current with one click.
Runs entirely on your machine
The Blender add-on talks to the Companion over localhost. Your meshes never leave your computer.
