Take the guesswork out of NMM and OSL. Place real lights around your actual model, see where every highlight lands, and match what you see to the paints already sitting on your shelf.
Everything below runs live in Chromatory Studio, on your own machine. No account, no upload, no subscription.
Printed a multi-part kit? Drag the parts in, nudge each one roughly where it belongs, and Chromatory snaps the mating surfaces together for you. Then export the whole thing as one merged STL, ready for the slicer.
Drop in your STL and light it the way a photographer would. Preview NMM (non-metallic metal) and OSL (object-source lighting) with real cast shadows, so you can see where every highlight and shadow will land before you commit a drop of paint.
Model shown: The Price of Magic, sculpted by Nerikson
Non-metallic metal lives or dies by where the highlights sit, and real reflections move every time you turn the mini. So lock them. One click freezes the highlights exactly where they are, and you can orbit the whole model while they stay put. Every angle becomes a painting reference for the same NMM.
Model shown: Lord Celestian Prime, sculpted by Rescale Miniatures
The full Chromatory studio is a local-first app that knows every paint on your shelf, matches colours with real colour science, and paints your actual 3D model so every angle agrees. The optional AI is a painting coach, not another chatbot: it runs on free local AI or the ChatGPT or Claude subscription you already pay for, knows your projects, and gives feedback on your WIP photos. The free demo is the full app with one project, and your shelf carries over when you buy.
Real prints under the Light Studio. It's the same interactive view you'll get on your own models.




Every miniature here is the work of its sculptor. The Price of Magic and A Moment of Rest are by Nerikson, Krymathor is by Flesh of Gods, and Lord Celestian Prime is by Rescale Miniatures. They're shown to demonstrate Chromatory.
Chromatory Studio lives on your PC. Models are never uploaded anywhere, your library stays in your hands, and it only talks to the cloud when you ask it to. The legacy browser tools work the same way.
The demo is the full studio with one project, and the paint shelf you build carries over when you buy. One-time purchase, DRM-free, on itch.io.
Chromatory started as two free browser tools, and they're not going anywhere: the Light Studio and the Assembly Workbench stay free and keep working. New features land in the studio.
