Do I need to know Blender?
No. NullFit lets you refit and fine-tune outfits with sliders — no weight painting, no mesh editing. If you do know Blender, it just saves you hours.
What does NullFit actually do?
It refits and fit-sculpts clothing so an outfit conforms to a given avatar — transferring weights, adapting the shape, and repairing clipping. It works on the clothing; it doesn’t reshape the avatar’s body for you.
Is there a free trial?
No. NullFit is a one-time purchase (Lite or Pro). We keep it paid-only on purpose — it keeps the tool sustainable and the licensing clean. Pricing is low and there’s no subscription.
What exactly do I get?
Two pieces: the Nullcore Companion (a Windows app that holds your license and runs the compute), and the NullFit Blender add-on. You need both, and they talk to each other locally on your machine.
Does my data leave my computer?
No. The add-on sends fit requests to the Companion over localhost; your meshes and avatars stay on your machine. The license is checked with our server only at activation and via lightweight checks afterward. We never collect your creative content and run no usage telemetry.
My antivirus flagged the installer — is it safe?
Yes. NullFit is an unsigned indie installer, so Windows SmartScreen and some AV tools are cautious on first run. Click “More info → Run anyway,” or restore from quarantine and add a folder exclusion. It’s a false positive from the licensing protection layer.
Which Blender versions are supported?
The Companion installs the plugin into the Blender versions it detects on your machine. It works across current and recent releases — just restart Blender after installing.
How do updates work?
In-app. The Companion notifies you when a new version is available and updates itself; the plugin updates with one click. You don’t need to re-download from Gumroad for new versions.
Can I use it on more than one PC?
A license activates on one machine at a time. If you change machines, reach out in our Discord and we’ll release your old slot.
