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 tab. Proxy options that use a simplified placeholder are configured separately when you export.
Adjust the level
Drag the Simplification slider, or type a percentage.
Watch Statistics update: face count shows the original count and the simplified count when simplification is active.
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:
Preserve texturing
Avoids simplifying where texture coordinates would change too much
Preserve normals
Avoids simplifying where normals would change too much, to keep the original shape
Preserve borders
Avoids simplifying where mesh borders would change too much
Per-object overrides
The global slider applies to the whole model. To simplify one object differently:
Open the Outliner.
Use the simplification control on that object.
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 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, 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.
