Video Tutorial:
Replace nodes with the current selected light by using the Context Menu.
In Revit create and align the position of your nodes to the trees in your project. Export those nodes as FBX. Import the FBX into your Lumion Scene and align the position with rest of your project.
This feature also works with SketchUp and 3DS Max.
Even though we don't officially support this feature for other 3D programs it might still work if they are able to export to FBX.
Made in version: Lumion 7.0 Pro.
