I’m currently making a map that uses multistory buildings that go below my terrain. I’ve cut holes in the terrain following this page’s directions: Landscape Materials | Unreal Engine Documentation
Everything works fine with my player character, however when i drop my navmesh in it breaks my paths in a weird way when it comes to the holes i cut.
The issue is that even when you apply the transparency the terrain still exists in that location and the nav mesh will still bump into that. The only way i manged to “fix” the issue is to raise or lower the terrain until the nav dispalyed a solid green path.
Sorry, I should have come back to answer this while ago.
