Note: this is a different issue I have been having then my other post. I don't usually post on the forums here, but I was recommended to do so, so I'm posting a few problems I haven't solved:

Anyways:

I have a large room and at certain points in time, enemies are not supposed to cross through the middle of the room, so I'm trying to find a way to disable a part of the navmesh or create a barrier that the player can run through, but the enemies cannot. I read that a collision box cuts the navmesh at any point its edges intersect with the navmesh, but I tried to do that and have the collision box very small and low to the ground so the player can run over it, but it would still cut the navmesh. However the enemies don't seem to have their navmesh cut. They just walk over the box like any other terrain. So is there anyway to disable a piece of navmesh?

EDIT: Just to clarify, I'm trying to disable this with papyrus, in game. On the other forums I got some answers about using the ck to delete navmesh, and I need to disable and reenable the navmesh in game.

Have you tried a navcut box over the area that you enable or disable by your script?
