Exclude certain parts of map from nav mesh

Is there a way to exclude certain parts from my generated recast graph?
I can’t use RecastMeshObj here since the floor is just 1 game object (mesh) and it’s divided by those rocks.


There’s no direct way to exclude that part. You could use a navmesh cut I suppose. But you’d need multiple to fit it to the contour.

It doesn’t consume a lot of memory or cpu power, so it doesn’t really matter if it’s still there.
