Hi 3dsmaxed.
Thanks for the contact and feedback

.
1. You can import parts only of a model, if you have split the model in to parts. Same
Reload (re-import) process as you have done for the whole model. So it's not possible to have some sort of breakdown of parts in Lumion of one Imported Model, and then select which parts need Reloading.
2. Unfortunately, no (assuming you have the public 7 day Trial from our web site). It's a one way path from
Start template to
Scene. That's not saying it is not possible. In Lumion Pro there is a
Merge feature that allows one
Scene to be copied in to another
Scene.
But you can change the
Terrain or paint a different terrain look using the
Terrain Paint preset (pic 1), as well as use the effects to do the same as in the other templates.
Are you aware there are two types of Trial edition available? Please see our
Knowledge Base Article:
Is there a Trial version of Lumion?
