I’ve been trying to figure this out for almost a year now, still found out nothing about it. I have no static meshes in my persistent level, only a PostProcessVolume and Playerstart basically. Still, some objects appear when viewing “path colliding geometries”. I tried rebuilding geometry, rebuilding path, but nothing helped so far and I couldn’t find anything regarding this via google either.
This is driving me nuts because it ruins the navmesh, and I see no reason why those meshes are there. It would be helpful to somehow view the name of these meshes or something, but they are not even clickable.
I’ve deleted everything from this level, then added a fresh NavMeshBoundsVolume. Then I generated geometry and the shapes came back. You can see below, there are no other actors than the navmeshboundsvolume and the generated recastnavmesh. Those have no collisions themselves.
I’ts a quite big project and i’ve been working on it for a long time, so I’m not sure when and how it happened, so it’s pretty hard to reproduce.
My suspicion is that it has to do with Instance Tool. It seems that instanced actors randomly have their root collision loaded into the geometry build. I have a lot of these geometries when loading the project first, but after reloading all levels manually, almost all of them disappear. Except this one.
I was hoping that theres a “sercet” option to hard reset build data, or somehow figure out what geometry is showing up. It would be amazing if these geometries would be labeled at least.
