The things inside the blue box will be cut away, not inside the white bounding box.
Rotating a navmesh cut around the X axis work, but sometimes not as you would expect since the navmesh cut is actually just a 2D object, and rotating that in 3D can give odd results.
Can you explain how it works then? since it is a plane? should i attempt to cover the parts I want cut from above? encapsulate? what’s the method to get the correct results I want?
