Video Tutorial:

Use the Context Menu to mark an Imported Model as terrain. This will make the Imported Model behave more like the native Lumion Terrain. Moving multiple objects and ALT-copying multiple models will also follow the contours of the Imported Model. Setting the height of the camera in Movie and Panorama modes will now also use the Imported Model.

Made in version: Lumion 7.0 Pro.
