In the Palette there's a Swap row: two color pickers — a from and a to — with a Swap color button beside them. Choose the color you already painted, choose the color you'd rather have, and press the button.
Every face currently painted the from color repaints to the to color at once. It doesn't matter whether those faces are one connected patch or scattered across the whole model — if it's that color, it changes. One move, no clicking around the mesh, no hunting for the bits you missed.
- You changed your mind about a color. The cloak's blue, you decide it should be green — swap blue for green and the whole cloak comes with it.
- You loaded a spool you don't have. Swap the placeholder color for the real filament you're going to print with.
- Two parts ended up the same color by accident and you want one of them moved off — swap it to something distinct.
- Matching a theme or a reference late. Recolor a whole element without re-doing the painting.
This is a flat, global recolor by color. If you only want to change some of the faces that share a color — say the left pauldron but not the right — don't swap. Paint those faces directly, or grow the new color into just that area.
- Open the painter and load your painted model — or click Demo and lay down a couple of colors first.
- Find the Swap row in the Palette. It sits with your palette chips and has two color pickers and a Swap color button.
- Set the from color — the color that's on the model now and you want gone.
- Set the to color — the color you want in its place.
- Hit Swap color. Every face of the from-color repaints to the to-color in one go.
- Not what you pictured? Press
Ctrl/Cmd + Zand the model snaps back to before the swap.
Both pickers are dropdowns of colors already in your palette — you can't swap to a brand-new color. To bring one in, add it from the library first, then swap.
- It's one clean undo. A swap is a single action — one
Ctrl/Cmd + Zreverts the whole recolor, however many faces it touched. - Your palette stays put. The swap repaints faces; it doesn't delete chips. The from-color is still in the palette afterwards — it just goes unused on the model. Tidy it up later from the palette if you like.
- To merge two colors into one, swap the color you want to drop into the color you're keeping. Both end up the same.
- Check before you slice. A swap can change how many colors actually appear on the model, which affects filament slots. Glance at the Layer preview and swap counter afterwards.
If you catch yourself clicking the same region over and over to recolor it, stop. If it's already one color, a single Swap does the whole thing — and undoes in one step if you don't like it.
