I'm fairly confused as to what you mean.
As morph said, is it the SIZE of the buildings your after?
or is it the pathing as pointed out by acc?
or is it the model file itself?
The "shape" is a bit too general :/ sorry. Please elaborate.
I wish to create a building where 16x48 is the model size and pathing map size. I tried making a path map 9x48 but unfortunately all it did was stop units from walking through it. But the units were still unable to attack the building from the perimiter.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
