Grid from imported model

I’m not sure whether this needs to be posted here on in the Terrain section but here goes:

I need to build an application that would be able to import custom models made in blender, and have some pathing algorithms applied to the surfaces available. For instance, I need to import a 3-story building and make NPCs move through rooms/levels using a pathing algorithm like A*.

My question is - can I generate some sort of grid/graph/something from the blender model, that I can later use for traversal inside jMonkey ?

Thank you.

I haven’t tried it myself but there is a navmesh plugin. Search (using the google search to the right) these forums for “navmesh” and maybe “critterai” and you should find some discussions about this.
