Navmesh Issues With Spacing - 4.6 / 4.7

[Defranco]

We're still having issues with version 4.6 and 4.7 beta in regards to Navmesh generating.

On a fresh install, with a fresh map....  using all default settings...  creating a simple room has the Navmesh about 64 decimals from a wall.  Or two tiles of 32ea (grid view default).

Which works out great for doorway spacing with the default scale size.  

However, when changing the map size to 4096x4096 to create a bigger game (creating terrain), generating Navmesh puts the spacing at 544 instead of 64 away from a wall, or 17 tiles of 32ea (grid view default).  Now most rooms don't get any Navmesh generated.   Deleting the terrain and re-doing Navmesh doesn't revert the space changes.

So the only way to get the Navmesh to work is to scale everything 500% so that the Navmesh can go thru doorways, which defeats the purpose of the larger map.

Am I missing something?
My understanding is that the Navmesh distance from walls is based on character controller radius, which remains the same (or should).

The navmesh will probably not support an entire 4096x4096 map. At that scale there are memory issues.
