hello. I try to make evade simulation. but, basically unity's navmesh don't support runtime navmesh bake. so, how to solved my problem? case: 1. run my program. 2. select file and load 3D model(*.obj or my custom model format). 3. create model mesh. 4. 3D model has multiple floor and linked stair or slope.(ex, building, cityhall, apartment) 5. initializing path or navigation data. 6. do pathfinding. any ideas? thanks for read. best regards.
