UE4Editor 4.8 Console Command

Hello folks,

Currently, I’m digging to figure out the console command that I can use in version 4.8 editor. I found “Quit” and “Exit” console command to terminate editor which neither works for me.

Also, I want to export the navigation mesh from map file without open editor. I found UE4Editor-Cmd execute file from underneath Engine/Binaries/Win64 but it also open editor with freezed console window. Are there any way to use unreal console command without GUI execution?

Extra Q:
I forgot to ask this one, I’m using “ExportNavMesh” console command to export navigation mesh from umap file. How to set its save path for exported mesh file?
Gimme some guild! Thanks.
