(UE4 illusory 4 modular 3D cliff rock scene. This package focuses on a group of modular cliffs. They will help you create realistic map edges, rocky coasts or inland cliffs that blend perfectly with the terrain. Each cliff module and two large rocks are equipped with a mask and two sets of two detail materials, which cover the top of the basic material and completely control their strength and opacity. Their scale is world-based, so the level of detail is preserved and consistent when scaling the parent mesh.)
