I’m also wanted to see the source code. As a new-ish programmer compile errors are making this a bit hard to get working.

In this walk, you talk about the CachedGrid that you used.
I wonder why is it needed if the MassNavigationSubsystem uses the FNavigationObstacleHashGrid2D to keep track of obstacles and locations of entities?

In theory, isn’t it possible to use this grid to keep track of the location?
