If it is anything like fallout 3. Which I am sure is much better. It will depend on what type of game it is and it must recycle back to original state if proper triggers arnt met… Need a plan of what you have next to occur. Navmesh are like a lines of patrols that you send out and repeat even if pattern isnt precieved as in a basic guad patrol. Or a NPC who if isnt asked ther right questions triggers the next sequence within a location an mission (usually havin an item to trigger). Look at the basic patrol of npc in the geck if you have it and are familure with it. It will give u ideas of what you can do. Take time get fallout3 (not through steam I have always had issues with them when modding). But get it learn the geck and basic patrols from there it will save u time of what you will not have learned.In other words you will come out with faster knowledge than freestylin of not know what to do period. If u need help with the geck I will help. Navmesh I cant wait to get in. I am stuck with cheesy fbx and obj,lol.
