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 that are unimportant 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.
- External Link: Skimp
- 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
- There is more information on the following page:
- External Link: Rhino Mesh Settings
1.7: 3ds Max
- Use the ProOptimizer modifier in 3ds Max to reduce the detail level of curvy models before exporting them to Lumion.
