Im stuck with character movement

Hello, I use the default scene of the top side view in UE4
Created landscape, squeezed a few hills, run - the character does not bring down the hill, only on the plane.

With all due respect your question isn’t really that clear can you please explain what you mean a bit more

i cant move on top of the hill, characters only moves on flat

already resolved, need to play with LightmassImportanceVolume settings

wait what… why would lightmass importancevolume effect character movement?

sorry - NavigationMeshBoundsVolume
