Hello. Since 3 days I am unsuccessfully trying to find way to generate navigation data to be used for 3d click to move in the scene (game level). The navmesh generators (like Recast) are fine except for I need ability to fall down (along vertical axis) from higher positioned, walkable area's edge. Imagine a flat square and a bigger square below it. I would like to be able to jump directly down from the edge (in any point of the edge where there is walkable ground directly below). The scene is created in blender, i got access to all the triangles obviously and that's no problem for me to pre-generate the data structure representing walkable areas, so it is not a problem if it's performance heavy to generate.
How can achieve that? All suggestions are appreciated, thanks in advance.
