Known implementing classes:
EnvironmentVolume, NavMeshObstacle

Interface for (primarily) dynamic objects which should affect the navigation mesh at runtime.

Used to split the navmesh poly with the shape provided. And then Interface_NavMeshPathObject will do the work for determining whether or not a path is valid IF you have PreserveInternalPolys returning TRUE. Otherwise those polys have been removed from the navmesh (e.g. a giant metal cube landing on the ground).
