Hi im Dave I did the kvatch navmeshing for skyblivion, I saw a tweet you guys need navmeshing and i thought I'd give a hand over here I can also do some landscape design and building placement but not really great at blender, I can do some mediocre scripting. I only was able to kvatch because i had some serious computer issues and the one listed as my comp specs is way out of Date.
I have an intel I-58300h 3.8ghz CPU. 8ms refresh 15inch lcd lcd display. Nvidia GeForce gtx 1050 3gb ddr5 24GB 2400mhz Dddr4
I have also been beta tester for blizzard Entertainment on their titles World of warcraft: wrath of the litch king,cataclysm, mists of pandaria, Diablo 3, hearthstone, and overwatch.
This is my navmeshing example .esp it does require skyblivion 2.0 Dev copy or later. Found it floating in the forums and the application requests an example.
