Navmesh bakes partially,

The Problem
I have a map containing a terrain. On it are several boxes which have a mesh renderer, mesh filter, and box collider.

When I bake the map, it only bakes the terrain. The boxes are ignored entirely. Unity bakes the terrain as if the boxes were never there. The terrain shows up walkable but the boxes aren't, despite being accessible.

Additional Information
I also have planes I want the agent to walk on, but they are not rendered. There are also not rendered (invisible) collider boxes too. Can they baked too?

 

Move your boxes on the same layer as the terrain to have it seen as the terrain.

 

Both the terrain and the boxes are on Layer 9, still doesn't bake?

 

screen capture that terrain, boxes and inspector of the bake parameters?
Try using the Navmesh surface component. It's a separate download from github.

 

Here is a link to the screen captures.

 

screen of the navmesh in the editor? My guess is the box is too high.

Try using the navmesh surface component.

 

The components worked, thanks
