I tested the navmesh template from the content examples, because the green fields did not want to appear in a different project. Here is a picture showing my problem:
So the green field didn’t appear on the top of the mesh, even though is seems to be the same as default ones. What is difference between them, that causes this issue?
Have you tried playing around with navmesh generation properties? There’s couple of things that could affect this, like CellSize and MinRegionArea. Also, this could happen if the problematic static mesh has been marked as navigation’s “dynamic obstacle”, which results in an actor projecting an area (like “unwalkable”) onto navmesh, but not creating new traversable geometry.
