Nav mesh area is VERY small. How do I resize?

Questions & Answers

I have a problem with the nightmare shooter tutorial. I noticed that when I ran the game, none of the characters would move. I tried nearly everything to discover the problem until today when I checked the nav mesh agent settings. Looking closely I noticed that the nav mesh (highlighted in blue) was the only area that the zombunny could move.

How do I fix this problem? I want the nav mesh to cover the entire map. I have followed all the steps from part 1 to 3 in the tutorial.

I fixed the problem and here’s the solution.

In the tutorial on page 10 it gave this instruction:

If this instruction is followed it will give you problems. You need to keep the Mesh Renderer Component enabled, Bake the Nav Mesh Layer FIRST and afterwards you can disable/remove the Mesh Renderer. This is how I fixed it and now everything is working fine mostly.
