Lumion Free 2 should be able to load projects from Lumion Free 1, but the sky has been overhauled, so you might need to adjust the Weather settings.
However, you won't be able to load Lumion Free projects in Lumion Basic/Ultimate, regardless of the version number.
Library file contents
Model.lib: The original imported model data including all materials and textures (so that you can always revert to the original by deleting any materials that you may have applied in Lumion).
Model.lib.inn: The thumbnail image for the object in the model browser window. To update a thumbnail image, select the object in the model browser window, place it in the scene, adjust the camera and select the object using CTRL + left-mouse button + rectangular selection. Then press CTRL and left-click on the thumbnail image to update it.
Model.lib.mtt: This slider values etc for the Lumion materials that you have applied to your model.
Model.lib.txx: Any textures that you may have applied to your Custom/Lightmap materials.
This file structure ensures that each model won't require any external files.
