As I wrote in a other message, my model is far from the insert point, so none of the terrains tools work

True, the terrain tools only work inside a 2048x2048m square. There's more information here:

Good morning 
Is there any plan to increase the size of 2048x2048 meters for the terrain ?
For urbanism and landscape 2048m is not always enough....
Thanks
Best regards

Yes we have tried it and got a Lumion exe file to run on Xbox with the controller, or the Kinect
Works well!

Hi Gilles, not that I know of. The texture resolution for the terrain would have to be higher for that to happen. And a higher resolution means less memory for the rest of your scene.

With Lumionauts constantly upgrading to cards with more memory, maybe some would like the option to increase the default terrain size.  I know I would!
