Before I start diving into unsing Navmesh, I just wondered if someone could offer some advice. Is navmesh really viable for mobile devices? My scenes will tend to have few static obstacles (or none), and only a handful of dynamically placed obstacles on a flat plane. Is it worth using Navmesh or should I just create my own simple navigation code? ie does Navmesh come with a large processing overhead for such a simplistic scene? Thanks for your time. James.
