Within the top down template I am trying to build a walkway. Identical meshes with same collisions can be walked on under z +400 units but not above (player character sticks to mesh).
Could someone please point me to the relevant value within the player blueprint?
The Navigation Mesh Bounds Volume (upper right) has a Brush whose size can be set in the bottom right. The brush dictates where the nav data can be built. And you can visualise it using the dropdown seen on the far left.
