Navmesh and doors

Hello, i have really annoying problem with navigation mesh.. I have a whole level with floors, doors and everything. When i bake navigation, floors get blue, but the path from one room to another where the door is, remains not blue. I have tried to remove the doors before baking the navigation, but it is all the same... AI cant get from one room to another.

 

The navmesh bake process includes only areas with enough horizontal and vertical clearance as walkable.

please check:
• Is the width of the door opening less than 2* "Agent Radius" in the bake settings?
• Is the vertical distance from door threshold to lintel less than the "Agent Height" in the bake settings?

- and adjust accordingly

 

Huh? So how do you bake through a doorway?

 

I had this exact same problem that when navmesh was baked the rooms could not connect. I found out that if the wall with the doorway was one object it would prevent navmesh connecting the rooms. The solution is to make a separate wall part for the upper part of the doorway wall and add a navmesh modifier component to it and then check the "Ignore from build" option and there you go!

You can get the Unity navmesh components from https://github.com/Unity-Technologies/NavMeshComponents

Have fun!

 

@GreaserMonkey, I have a little different setup, but basically the navmesh does go through the doorway even when the room walls / doorway are a single object. I thought exactly the same thing like you, that I might need to separate it into multiple objects, but nope. I punched a hole by extruding / erasing faces.
