// What it does
When the marked area is non-empty, Simplify now decimates only the marked triangles. The rest of the mesh is left alone.
// When to use it
- Models that mix high-detail and low-detail surfaces — figures with plinths, vehicles with flat panels and detailed greebles.
- Trimming triangle count on the inside or back of a model that won't be visible.
- Speeding up the painter's frame rate by simplifying a busy region you've finished painting.
// How to use it
- Mark area → drag around the region to simplify (e.g., the demo's base).
- Export tab → Simplify now. Status reports tris removed.
- Orbit to verify — marked area is lower-poly; the rest stays sharp.
// Tips
- Forgetting to mark first? Simplify now runs on the whole mesh — usually not what you wanted.
- Stale mark from earlier in the session can trip you up. Clear if in doubt.
- Too aggressive? Even on a marked area, a high threshold collapses real detail. Use Preview only first.
