// What it does
Edge-collapse mesh decimator driven by a flatness threshold. Preview only means no triangles are removed yet — the orange overlay shows which ones would collapse if you ran it for real. Drag the threshold slider to see the trade-off live.
// When to use it
- Tuning the flatness threshold before committing to a destructive simplify pass.
- Sanity-checking that the simplifier targets flat areas (chest plates, plinth tops) and not your detailed regions (faces, runes).
- Doing a quick 'how aggressive can I be?' exploration.
// How to use it
- Export tab → Simplify. Set Flatness threshold to ~2°. Tick Preview only.
- Orange tint covers tris that would be collapsed.
- Drag the slider — preview updates live.
- Untick Preview only + click Simplify now when you're ready to commit.
// Tips
- Forgetting Preview only is on? Click Simplify now and you'll get a real simplify on the previewed tris (which is fine — just be intentional).
- Cranking the threshold high just to see is safe in preview mode — but drop it back before committing.
