Can't fall on edge , static mesh collision problem

as you can see in video i model simple low poly island shape in maya and import as fbx (also tried with obj) , my character is collide with ground of the island but if i walk near edge of island character stuck , doesnt fall . i check collision object it looks ok, any idea what causes this?

thnks.

look at your character blueprint and it’s movement component. This is most likely that the can walk off edges box is unchecked.

somehow it was unchecked. thnks.
