Landmass physics material


I created a landscape using blueprint brushes (landmass) that use multiple physical materials. The purpose is to change the behavior of a lidar (raycast) when it hits different types of surfaces.

Using the manual brush (drawing on the landscape by hand) gives me the desired effect: The correct physical material is detected by the raycast:

But if I use a landmass blueprint brush, the raycast does not detect it:

Please note that I am using the same layer in both situations:
