I had troubles with fixing/editing nav meshes in the past, but the guys here at TF2 helped me a bunch at it and as of today I'm able to fix/improve the navigation meshes on many official maps.After some testing, I managed to get a medic bot to follow me all the way to mid so its not like they physically can't walk out of spawn.
Question: Once/if I solve this, will the nav mesh be permanent such as uploading the updated .bsp to the steam workshop because the nav mesh is a different file?
Also in MvM, if a robot goes out of navmesh it will be teleported to the closest nav area.You do know of the failsafe navigation mode bots use when they end up on areas without the navmesh right? They just run in a straight line towards their goal. So managing to get a medic bot to follow you does not mean that the navmesh is fine.
