When my program was generating navigation meshes for my geometry, and the extent is 5000x5000 (m), with a cell size of 5.0 meters, it has to generate 250,000 cells, which makes my computer halt, the target object is a truck, which has a radius of about 20 meters, should I give the cell size a value of 20, because I don't really want to use this navigation mesh on one type of vehicle only. I want to use it for vehicles like cars, which has only about 5 meters in radius... the generation speed is a problem while the memory consumption is another.
Any ideas how to improve this?
Thanks
Jack
