The landmass brush doesn't effect the landscape when I add conponents to the landscape.

The landmass brush doesn’t effect the landscape when I add conponents to the landscape,I still can see the spline of the brush, but nothing happen on landscape。I use Unreal Engine 5.03 and converted to world partition.

I also encountered this problem, and my solution is to delete LandmassBrushManager and delete Landmass Brush, and then add Landmass Brush again

I use UE5.3.2
