Terrain Surface Materials List Component
The Terrain Surface Materials List component defines mappings between surface types and render materials. You can use this to change the appearance of a surface type within different areas of your game. When you assign a material to a surface type, all the visible surfaces of that type, within the bounds of the required Axis Aligned Box Shape component, will adopt that material.
Usage
Select the surface type tag using the SurfaceTag drop-down menu, then assign a material by clicking 
and choosing a material, or by dragging a material from the AssetBrowser window.
