You have imported about 100 custom models over time.  You have just realized Lumion has a feature to save the Imported Model to a Category.  For example Plants or Cars or Furniture.

You would like to know if there is a way to create those Categories now, being after the fact of importing the models.

Here's how:

1. Make sure Lumion is closed.

2. In Windows File Explorer go to the folder Documents\Lumion [version]\Library.

3. Create new folders to put the model files in (e.g. people, cars, furniture, etc...)

4. Move the Imported Model files to those desired folders.

There are 4 files per model (.lib, .lib.inn, .lib.mtt, .lib.txx).  See article:

• 知识库: Where are scenes and imported models saved to in Lumion?

5. Restart Lumion in order to refresh the Imported Model Library browser window.

Note: 

Projects that have already been saved with the Imported Model in a different Category folder will load the model from the Project file back to the source Library folder.

Applicable To:

Lumion 8.0 and newer.
