Import Blender Object as map, and Ideal size for Loop.

Would it be possible and/or practical to first make a make a level in Blender, and then use that object as a map in BeamNG? If so, what would come over, just the shape, or the textures as well?

Also, what is the ideal size for a loop-de-loop, so that it will work with most vehicles?

 

I am unsure how to answer the first question, but with the second question, pick a speed and then watch this and backwards calculate.

I was referring more towards ground clearance than speed, but thanks anyway, I'll go watch it. (Unless he does talk about ground clearance, then double thanks or something.)
