I've seen other posts regarding this, but I haven't found a solution.
I created a very simple door (four bars) in WED and built it. The "passable" property flags were unchecked for the four bars.
In my level, I used "Add map entity" to add the object. In the object's Properties, I made sure Passable was unchecked. I also tried checking only BBox, only Polygon, and both BBox and Polygon.
No matter what I do, my model entity passes through the door. The model does not pass through other objects (e.g., boxes, cylinders, model, etc) on the level, just the objects added with "Add map entity".
Ideas?
Thanks!
