Btw, this is just a CT city block I used for the demo. I didn't place all those buildings. On the one I will build into the MA terrain, I will hand lay them all, making sure there are plenty of killzones & fields of fire to work with by all sides.
To answer Larry's earlier question, I've only used the TE for this. I'm avoiding the OE since we are not able to use it to build anything for MA terrains (no non-default objects or shapes), which sucks, but is necessary for stability. Can't have an entire arena crash because of one screwy object.
