Take a good look at the picture above. It’s my definition of NavMesh Hell. It involves three cells and stairs on top of that. It took me half an hour to finish. With Oblivion’s Construction Set things like these took a couple of seconds. We had something called PathGrid, which specified where NPC’s could walk. Followers could still follow the player around wherever he went, even without PathGrid. Not so in Skyrim. If there’s no NavMesh, no NPC can walk on there, and that includes followers. Yay!
It’s my honest opinion that NavMesh doesn’t make NPC’s act more natural than in Oblivion either. They still walk into statics, stand on chairs and take weird routes. So what’s the gain really to move over to this beast of a system? Just time-consuming, completely non-understandable and unintuitive for new modders and generally irritating with error messages popping up even after you’ve done the “Check NavMesh” routine. It’s a real turn-off, I tell you.
So many things with modding this one have gotten so time-consuming and just plain no-fun.
