@bergice, Menu options so far:
File
-Open Project [not working yet]
-Save Project [not working yet]
-Import [3DS/DBO/X]
-Exit
Edit
-Edit Material [Smoothing only so far]
Scene
-Sky
--Add/Remove [Add/Remove DarkCLOUDS]

--Edit Ground [Edit ground height]
-White Room
--Add/Remove [Add/Remove white 'showroom']
--Edit Ground [Edit ground height]
Lighting
-Create Lightmaps [self explanatory]
-Automatic Lights [the only option at the moment as I've yet to add in manual lighting...]
At the moment the scene scales to the size of the imported model so you don't need to worry about the model you are importing as the scene and lightmaps work out according to the size of the model.
Here is the current version (attached) please let me know what you think and any bugs you find...
