Chromatory — Light Studio

Plan light placement for NMM and OSL: load the STL you print from, place lights, pick a look, and copy the highlights. Runs entirely in your browser — the model is never uploaded, so any size your machine can handle is fine. · 🧩 Assembly workbench · 🔔 News · Terms

Drop an STL here or choose a file

binary or ASCII STL · stays on your device

Orbit with drag/pinch · wheel zooms · tap a handle for X/Y/Z arrows · Del removes the selected light · Ctrl+Z undoes. Sideways model?

🎨 Look

Responds to your lights:

Fixed idealized reference (ignores lights — the shapes to copy):

Color

Metal Rough

💡 Lights

Ambient room light — brighten to inspect, dim for dramatic OSL

Floor the table the mini stands on — its colour tints every light's bounce

Shadows the model blocks light — turn off on weak GPUs

Light source dots the glowing orbs where your lights sit — off shows just their light (saved renders follow this)

Shadow colour Strength painters shade toward a colour, not black — try a cool blue-violet

🖌 Regions

Paint areas on the model (armour, cloth, skin…), then light one up on the render.

💾 Rigs

A rig saves everything: lights, look, colour, ambient, floor, shadows — as a JSON file you can reload here or in the app.

📸 Capture

Save the current render as a PNG — your painting reference.

🧩 Scene

Add more STLs to light a composed scene (a base, scenery, a second mini). Click one to select it, then drag its gizmo to move or turn it. Scene models are session-only — save a render to keep the composition.
