AI Paint.

AI Paint colours a whole model for you in one go. You tell it what you want two ways: give it a reference photo and it matches the picture, or type a prompt like weathered bronze, teal glow, cream underbelly and it works out the colours from your description.

It paints the entire model, then loads the result straight back onto the canvas as editable colour regions — not a locked image. The Colours slider sets how many colours it uses. When it's done you tweak anything you like with the normal tools and export as usual.

AI Paint sends your model up to be painted, so it's the one part of Layerpaint that isn't fully in-browser. Painting by hand stays local.

• You want the whole model coloured fast, without working through it region by region.
• You have a reference to match — a painted figure, a real animal, box art.
• You want a scheme you can describe but wouldn't want to click out by hand.
• You want a starting point to refine, rather than painting from grey.

1. Open the painter and load a model — or click Demo for the sample.
2. Open AI Paint from the bottom of the left rail (or the ✦ AI pill).
3. Give it a reference photo, or type a prompt. A photo pins the look down; a prompt gives you more room and shades.
4. Set the number of colours with the Colours slider, then click Paint it.
5. Wait a few minutes. The painted model loads back onto the canvas, replacing the grey one.
6. Tweak and export. Fix a seam or recolour a panel with the usual tools, then Export a Standard 3MF and print in colour.

Your first 2 paints are free. After that AI Paint runs on credit packs ($4.75 for 5, $16.97 for 20) — separate from export credits, and one flat credit per paint no matter how big the model.

• Want an exact match? Use a reference photo. Whatever the picture looks like is roughly what the model comes out looking like.
• Want a look that doesn't exist yet? Describe it. Prompts are happy to give you shades rather than flat blocks.
• Not quite right? The result is editable — recolour a region, redraw a seam, or Magic Fill over a part before you export.
• Big model? It still costs one credit. Size and detail don't change the price.
