Question Baking a procedurally generated floor

So I'm working on a project with a procedurally generated maze, and need a way to bake a navmesh on the floor. I have a navmesh surface on the floor prefab but it just bakes a square and won't connect to the others. I tried following this video (

) but still couldn't figure it out. Any help would be greatly appreciated!

 

Anyone?

 

You can build you navmesh at runtime, and while there are several ways to go about this, the one that scales the best is if you keep track of all the things that should contribute to navmesh, you can update the navmesh by creating a list of sources as you're loading stuff in. Here's a crude example you can try to experiment with:

Code (CSharp):

1. var sources = new List<NavMeshBuildSource>();
2. foreach (var item in meshRenderers)
3. {
4.     sources.Add(new NavMeshBuildSource
5.         {
6.             area = 0,
7.             shape = NavMeshBuildSourceShape.Mesh,
8.             transform = item.transform.localToWorldMatrix,
9.             sourceObject = item.GetComponent<MeshFilter>().mesh
10.         });
11. }
12. var bounds = new Bounds(Vector3.zero, new Vector3(2000, 500, 2000));
13. var agentId = 1;
14. NavMeshData d = new(agentId);
15. NavMesh.AddNavMeshData(d);
16. var settings = NavMesh.GetSettingsByID(agentId);
17. NavMeshBuilder.UpdateNavMeshDataAsync(d, settings, sources, bounds);

Now, the NavMeshData you only create once (per agent type you wish to support) but you call NavMeshBuilder.UpdateNavMeshDataAsync everytime you create a new NavMeshBuildSource that would change your navmesh.
