Thanks a lot! These models were so tempting, that I couldn't resist working on them. Once you've done it, you have a nice collection of high class sci fi models you just have to put in your scene. This is definitely not the last image that uses some of those models.
Btw, placing lights in Terragen is a pain in the a§§!! So for this scene Kitbash's green house model is located at 0,0,0. I loaded the same OBJ (for TG I converted it to TGO) into 3ds Max at the same location, placed some omni lights where I wanted them, and exported them as FBX. Importing this FBX gave me a bunch of lights at their appropriate places. The only thing, that's quite inconvenient, is, you have to set their parameters before you export them from 3ds Max (or whatever 3D app is used). Editing each and every light in Terragen separately is no fun. Especially when you have a scene with 60 lights (like in my first Minerva attempts, where I tried to put almost all models into the scene.
So fortunately in 3ds Max there's a tool named Light Lister, which is fantastic, since you can edit all selected lights at once. If you find you're lights are for example too dark in Terragen after importing, it's easy to edit them in Max, export them again and import them again in TG. It's a matter of less than a minute.
Some sort of a Light Lister would be cool in Terragen
And attaching lights (or objects) to other objects or whatever, or grouping them is a feature I desperately miss in Terragen. Actually I think, this is quite an essential feature for a 3D app.
