How do you reduce the complexity of a model before importing it in Lumion?

1. Here's how

If you try to import a model that is too detailed for your computer, it might take a long time to finish the import process.

To speed up the import process, we recommend the following steps:

1.1: Hide surfaces or objects that are unimportant for your visualization in your 3D/CAD software before importing the model in Lumion.

1.2: Export the model via LiveSync rather than via .DAE format as it is faster and requires fewer resources.

1.3: Consider splitting up the model in several parts and import them as separate models in Lumion.

1.4: SketchUp

Skimp: This tool reduces the detail level (polygon count) of your model and includes an importer with a texture placement material remap tool.

Material Resizer: This tool checks the material texture sizes in your model and allows you to quickly resize them.

CleanUp3: This tool cleans up and optimizes your SketchUp model.

1.5: Revit

The Surface Smoothing slider lets you define how detailed curvy surfaces should be.
Setting it to the maximum value can have a serious impact on the time it takes to import the model as well as on performance and render speeds in Lumion.
For that reason, we recommend setting the slider to the lowest possible value that still ensures that curvy objects look reasonably smooth.

1.6: Rhino

Use the Density setting to reduce the smoothness of curvy models before exporting them to Lumion:
Rhino top menu -> File -> Properties -> Mesh -> Custom -> Density -> 0.0

1.7: 3ds Max

Use the ProOptimizer modifier in 3ds Max to reduce the detail level of curvy models before exporting them to Lumion.
