To preserve the proportions between 3D models in Harmony, you should set all your 3D models to the same scale factor. Once you've determined the ideal scale factor for your project, you can set the default scale factor to apply to 3D models when you import a 3D model into a scene.
In the top menu, select Edit (Windows/Linux) or Harmony Premium (macOS) > Preferences.
The Preferences dialog appears.
- Select the General tab.
- In the 3D Models section, in the Default Scale Factor field, type in the default scale factor for your 3D models.
Click on OK.
From now on, when you import a 3D model, its scale factor will automatically be set to the scale factor your just entered.
