I have an NPC and there are alot of walls as the NPC is in a house. The NPC should be able to completely ignore the walls and be able to go through them.
However, I have tried putting a PathfindingModifier in each wall with PassThrough set to true and that doesnt work.
I have also tried putting all of the walls in a CollisionGroup and setting the NPC and the walls to not collide.
The “last resort” solution would be to only load the walls on the client, and the server wouldnt have any walls.
