It's been a while, here's what Copernicus Painter has been up to
A lot has happened since the last update. Here are the most significant improvements:
- Layer reordering: You can now drag and drop layers wherever you want, with a visual indicator showing exactly where the layer will land. Undo/redo works correctly through reorders too.
- UDIM support: The big one. Copernicus Painter now supports UDIM workflows. Geometry gets split per tile automatically, each tile gets its own COP chain, and you can paint across a full UDIM set. On export you can either export per group per tile, or merge all groups sharing the same UDIM space into a single texture per tile, with proper UV coverage masking so groups blend correctly at their boundaries.
- Undo/redo overhaul: This was a long battle. Sliders, opacity, blend modes, channel toggles, mask operations, all now sit correctly on the undo stack. The viewport and layer panel stay in sync through undo/redo.
- Height channel: Added a height/displacement channel with a remap option and a dedicated bake stash path.
- Bake preview: You can now preview baked maps directly in the viewport before committing.
- Fill mode: Paint masks can now be initialized as fill white or fill black on creation.
- Export window: Texture export now happens through a proper export panel with format, resolution, template presets, and per-channel control. 

I put together a video painting on a gun with UDIMs, it covers most of the new features and gives a good idea of where the tool is heading.

Any progress on this? I've been working on some techniques for painting with paths if you're interested

I’m making pretty good progress right now. The plan is to focus on the UI so that it’s as artist-friendly as possible. After that, we can implement additional features like yours. I’ll try to share a beta version soon. I’d be interested to see what you’ve got .
