            # WARNING: Directly changing landscape layer weights via Verse 
            # usually requires using Landscape Component APIs or Material Parameters.
            # Here is the conceptual flow:
            
            # 1. Get the Landscape Component under the player
            # 2. Update the Material Parameter to increase Mud weight
            
            # Since we are keeping it simple, we'll just log it.
            # In a real build, you'd use:
            # MudMaterial.SetScalarParameterValue(MudIntensityParam, 1.0)
