Small agent can't enter the hallway, how to fix it?

bbbhh

That little agent can’t get in the hallway, only moving up down at current position, even the hallway space is higher that the object radius.

If I put the object in the center of hallway, that object can get out by following the line, but strangely can’t enter the hallway.

How to fix it?

Hi

I think that your AIPath → Pick Next Waypoint Distance field is a bit too high. Try to lower it a bit to make the agent follow the path more closely.
