Ultimate Navigation is not just HPJ Pathfinding Pro 2.0. Ultimate Navigation will make HPJ effectively obsolete. HPJ while allows 3D pathfinding by projectile obstacles onto a 2D grid, it is still in the end, a 2D Pathfinding Solution.
Ultimate Navigation will handle far more pathfinding and navigation needs than HPJ, it will handle 2D navigation styles Grid, Hex and a platforming specific solution. It will handle 3D solutions as well, such as 3D grids, Nav-Mesh, Node Navigation, a roadway for vehicles specific pathfinding as well as a proprietary volume navigation akin to a reverse Nav-Mesh.
Ultimate Navigation is a project that is currently a work in progress. If you purchase HPJ Pathfinding Pro, you will get a copy of version 1.0 Ultimate Navigation for free before HPJ is removed from the asset store.
