3) is the sapce in Lumion 4.0 Pro bigger than in Lumion 3.2?
If you are referring to file size on harddisk, Lumion 4 is larger as there is more content included. The exact size for download and when installed on a harddrive will not be known until final packaging and release.
As Morten mentioned, the editable terrain is the same. Note however that where you need more than that, you can import your own terrain from 3d modelling applications as a mesh. You do this in the same way to import a building.
Lumion world size is 42 km radius. The editable terrain is 2048mx2048m.
