I have then created an “enemy” who is supposed to target my protagonist by using steering (behaviour: path following, target object:protagonist, navigation mesh: Navmesh).
I have chosen the maze and then try to use blenders “Build navigation mesh”. When I press “Build navigation mesh” it creates a new layer and names it “Navmesh”. The problem is that this layer is empty. It has not created a navigation mesh.
So when I add this newly created mesh to the steering of my “enemy” and starts the game, the “enemy” does not move.
I have tried following different tutorials on YouTube (https://youtu.be/aMWeTXL98mM), but with no luck. I see when others create the navigation mesh, they get a colorful area where the object is supposed to move. In my case, I get no colorful areas.
i seperated the bottom plane(grid) from the cube “wall”, and made them into seperate objects. And then just built it from the bottom plane. you can see if you select it in the file that I seperated the objects. P in edit mode will seperate into seperate objects btw.
I separated the bottom plane(grid) from the cube wall, and then tried to build the navigation mesh from the bottom plane. I still experience the same problem. The new navMesh layer is empty
It looks good in the NavMesh2.blend file you made, but I still can`t create navMesh.
I had a similar problem, and I was using Blender 2.75a. After countless attempts, I thought about switching to another version and trying, and it worked when I tried doing the same with Blender 2.76 RC. I guess using another version should work in this case as well.
