// What it does
Tick the box. The painter keeps the full-resolution mesh in memory — paint, undo, layer view, and discard checks all run on the hi-res copy. When you click Export 3MF, the simplifier runs once on the way out, producing a decimated 3MF. Your working file is untouched.
// When to use it
- Models you'll keep editing — paint always benefits from more triangles, but the slicer doesn't need them.
- Reducing 3MF file size for sharing or storage.
- Speeding up slicer-side processing without sacrificing painter accuracy.
// How to use it
- Export tab → Simplify. Tick Simplify at export only.
- Paint normally — the in-viewport mesh is unchanged.
- Click Export 3MF. Status reports both original and post-decimation triangle counts; the downloaded file is the smaller one.
// Tips
- Combined with manual Simplify now means you simplify twice on export. Pick one approach.
- Same flatness threshold drives both modes. Tune via Preview only first.
