Recast graph not connecting areas separated by openings

  • A* version: 5.3.8
  • Unity version: 6.0

I have two areas separated by an opening (show in the picture, wall with a hole where door should be). But when I scan the Recast Graph, it’s not connecting these two areas. Am I missing anything? Pretty much all the settings are defaults.

That wall probably has a box collider on it, I’m assuming? (Let me know if it’s a mesh collider) You’ll want to add a RecastNavmeshModifier in that doorway possibly?

It could also be that the door is just slightly too narrow for the navmesh to go through. Try to either make the door wider, or reduce the Character Radius in the recast graph settings.
