Like I said somewhere else here, I've had a closer look to that goblin editor and i'm a bit startled as to what you can do with it!
As far as I found out, you can only tweak values for some controller parameters such as light illumination, controller for the rendering engine, etc. Basic stuffs, so to speak. Nowhere could I find anything to add waypoints for example, move them, add even existing 3d model into a scene (say Uboat interior for ex.), no apparent way to import 3d model and etc.
I'm afraid this goblin "editor" is more of a viewer than anything else

not that near to what S3D was for SH4 in its latest states.
As far as it would seem, I'm afraid we'll have to once again praise and wait for a talented programer like skvasjer to develop our own editor!
