trying to import custom doodad=green box

[Herod]

I would like to know abou walkable walls....
I´ve imported one of a map that is walkable but in my map it isnt. What I must do to the units walk in stairs in walls??

There is a destructable object editor field that makes the destructable model walkable when enabled. It is used by elevators, bridges and ramps by default.

Easiest option will be invisible platforms (the small version). Stack them tightly together, select them all, press Y to make them all the same height and then raise them to the desired height with ctrl+page up.
