# Simplification

Simplification reduces the face count of a model so SketchUp stays responsive. It is especially useful for dense scanned assets, high-poly DCC exports, and large vegetation or furniture packs.

The controls live in the [**Geometry**](/geometry.md) tab. Proxy options that use a simplified placeholder are configured separately when you export.

## Adjust the level

1. Drag the **Simplification** slider, or type a percentage.
2. Watch **Statistics** update: face count shows the original count and the simplified count when simplification is active.
3. Check the viewport (try **Monochrome** mode) to judge shape fidelity.

Higher simplification means fewer faces and a lighter SketchUp model. Lower values keep more detail.

## Magic wand

Click the magic wand next to the slider to let Transmutr choose a level that balances fidelity and performance. You can still fine-tune the slider afterward.

## Linear vs non-linear slider

Toggle **Linear** / **Non-linear slider** when you need finer control near the low or high end of the range. Non-linear spacing makes small adjustments easier in the region you care about most.

## Preserve options

When simplification is active, you can enable:

<table><thead><tr><th width="196">Option</th><th>What it does</th></tr></thead><tbody><tr><td><strong>Preserve texturing</strong></td><td>Avoids simplifying where texture coordinates would change too much</td></tr><tr><td><strong>Preserve normals</strong></td><td>Avoids simplifying where normals would change too much, to keep the original shape</td></tr><tr><td><strong>Preserve borders</strong></td><td>Avoids simplifying where mesh borders would change too much</td></tr></tbody></table>

## Per-object overrides

The global slider applies to the whole model. To simplify one object differently:

1. Open the [Outliner](/outliner.md).
2. Use the simplification control on that object.
3. Set a level for that object only (or reset to fall back to the global slider).

Per-object levels take priority over the global setting. Transmutr warns in the Geometry panel when some objects have overrides.

## Tips

* Prefer the magic wand as a starting point, then nudge the slider.
* Use [proxies](/exporting/proxies.md) when you need full detail at render time but a light viewport in SketchUp. See Proxies (including the "*Simplified geometry*" placeholder type).
* In [Studio / Creator batch sessions](/batch-conversion.md), simplification is shared across tabs unless you override it per model.
* From the CLI, use `--simplificationLevel`, `--simplificationAuto`, and the preserve flags. See [Command-line interface](/exporting/command-line-interface.md).
