Skyrim Modding Part6 : Navmesh

Navmesh

The NavMesh in creationkit was actually quite easy to work with, though some problems occurred on the way. Navmesh is a plane that is put on top of your ground to show where the AI can walk, and is often shown as a red overlay in the scene. It was easy to create it in the interior scene, as the ground was flat. I simply clicked the generate navmesh button, and with some tuned settings it projected itself down on the ground. There were some problems around the doors, and the puppets had some trouble getting into the different rooms. It was fixable with one very impressive feature in CreationKit, that allowed me to merge and edit the faces and vertexes of the navmesh, and tweak the small hallways so it got big enough for the AI to walk through.

It was alot more problems with  the navmesh on the exterior scene, as I did not want to screw up the already laid navmesh out there. I had a really complicated entrance with a gigantic stairway to the door, and getting the navmesh to fit on top of it simply would not happen, so I took the easy way out and added a much kinder entrance
