BeamNG and custom maps.

Hey guys, quick question.

I was just wondering if BeamNG will support user created maps (I wouldn't be porting maps from other games, more than likely making maps of my own.) if so, what software should I use? (I currently have Blender and Sketchup, but if I have to use Cryengine 3, I may not be able to, it doesn't seem to want to play nice with my AMD based desktop.)
what formats would it support? the same idea as models for cars? will the maps support the same featureset or require the same featureset of Cryengine? or whatever engine BeamNG gets put on (if I do remember correctly, BeamNG is to a degree, an addon for game engines.)

 

It is completely run in Torque3d. I'm pretty sure that is what hutch makes maps with, too.
