Map exporter?

#1 I believe there is one, though you will have to most likely adjust your workflow in such a way that you might as well be using Constructor or Quark or Radiant. At least that's the way it is with most map exporters from polysoup applications. People just expect to create their geometry the same way they do everything else in their app and click export...and have it work. Better to use polysoup...unless you want lighting. Lighting is pesky.

#2 I was afraid you were going to say that... I just think that Blender would be an easier for me since constructor doesn't have an easy edit mode...

#3 Yeah, the vertex mode in constuctor is really hard to use. Do anything to a vertex, and you've got 50 concave shapes...
