NullFit Trial

The no-commitment way to try NullFit's refit on your own model.

24 hours · nearly full Pro · free

NullFit refits clothing onto 3D models in Blender. This trial runs nearly the full Pro toolkit for 24 hours, on your own models and outfits, so you can judge the real quality before you decide. Downloaded the trial before? You can run it again now.

These videos show the complete Pro pipeline. Live-preview sculpting and batch refitting are Pro-only; everything else you see, the trial runs.

What the trial runs
  • All four refit algorithms — Standard, Better, Adaptive, and Snap. From clean humanoids to anthro, dragons, and custom proportions.
  • Fit cleanup — Auto Clipping Repair, Shrink to Fit, Symmetrize, Preserved Faces, and the Smoothing Workshop.
  • Surgical control — Shape Key Filter and per-region refitting.
  • Your model, your outfits — it refits real clothing onto your own body in Blender, not a canned demo.
  • Online — the refit is computed on Nullcore's server, so you need an internet connection while you use it.
  • Metered — the trial is capped per day so it stays a trial. Enough to fit a few outfits and see the quality for yourself.
Not in the trial
  • Live Preview sculpting — real-time sliders, presets, clipping heatmap, and Fit Check score.
  • Multi-outfit batching and multi-body wardrobe.

Both live in Pro. Link below.

How it works

A Blender add-on does the work in your scene, paired with the Nullcore Companion app. Install both, and the trial refits through Nullcore's server. No license key to buy and no subscription to run the trial. An internet connection is required.

Who it's for

Want to try NullFit's refit on your own model before buying? This is it: nearly the full Pro toolkit, for 24 hours. If you need live-preview sculpting, batch refitting, or a permanent offline license, go straight to Pro.

Ready for everything?

NullFit Pro is the permanent license. It adds live-preview sculpting and multi-outfit batching on top of everything the trial runs, works offline, and it's yours for good. A job that used to eat 5+ hours per model now takes about 30 minutes.

FAQ
Do I need to know Blender or Unity?
No. NullFit lets you refit and fine-tune outfits with sliders, no weight painting, no mesh editing. The Trial runs as a Blender add-on; the paid versions also come in a Unity version. Either way, if you know the software it just saves you hours.
What does NullFit actually do?
It refits and fit-sculpts clothing so an outfit conforms to a given model, transferring weights, adapting the shape, and repairing clipping. It works on the clothing; it doesn't reshape the model's body for you.
How is NullFit priced?
You can start free on the Trial, which runs nearly the full Pro toolkit for 24 hours, capped per day, so you can fit real outfits and see the results before you buy. When you are ready, the desktop versions are a one-time purchase, the Blender add-on or the Unity version for $35 each, or both bundled for $40, just $5 more for both engines. Or run the same Pro tools in the cloud, with nothing to install, on a Cloud subscription, $10/mo for Blender or Unity, or $15/mo for both bundled.
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?
It depends on the fit. For local fits, the Blender Pro refit runs entirely on your own computer and your meshes are never uploaded. Server-side fits, the Unity tool, the Cloud plan and the trial, send the specific body and outfit meshes you select to my server to compute the fit and return the result; those meshes are processed only to perform that fit, are not stored afterward, and are never used for anything else. Either way, your other models, project files and session contents are never read or uploaded. The license is checked with my server at activation and via lightweight checks afterward, and I run no usage telemetry. The privacy page has the full detail.
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 then 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 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 my Discord and I'll release your old slot.
What happens to my Pro license if you stop working on NullFit?
Your access stays. Blender Pro is a one-time purchase, and I'm building a continuity plan so legitimate license holders keep full access even if I step away or the project winds down. The goal is simple: your access should not depend on me being around to keep it alive.
