Collision Sizes

Ive been trying all day to get this right. In the RPG im working on, ive changed the sizes of alot of human buildings to about double. This is to make them more proportionate to the units. Looks great except for the fact that units can walk into the building. Like right through the wall. No matter what I set the collision size to it still seems to be the same size on the map. Has anyone else gotten this problem and has maybe been able to fix it?

If you dont know what im talking about, turn on pathing view and small grid. Then make the human castle about double size and go place it on the map. You will notice the pink area (collision box) is still the same size, even if you change the value in the unit editor.

Its the pathing map you need a diferent one. Collision size works for units when avoid obstacles, they see that if they come with in X &X range they will collide with the unit, however this isn't the case becuase the building pathing map is only 16x16 while the building is 32x32. In short Use we-enhanced and use the biggest pathing map :)

it doesnt, black dicks WE does stack, but in game, the collision sizes are the same.
