Im wondering is there a way to actualy make theb size of each grid Unit smaller.

cause im having a realy hard time getting the canals right for my theed map because of the terrain i cant make steep anough Canals to fit the models good.

Im using NAb2_prop_railing and NAb2_prop_railing_pill becauseb they are the only ones that allighn with the bridges.

So can this be done!??

Not really. That's what pissed me off when I was working on Theed. At the end, instead of using terrain to cover the the ground, I just stuck some buildings there and cover the holes.
