This material is a mix of man-made stone ground and a layer of thick moss, which can often be found in traditional Japanese gardens or environments with ruins.
The contained material is of high quality (2048x2048), uses the Physically Based Rendering approach and is ready-to-use with the Standard Shader in Unity. Of course, all necessary textures are provided, so feel free to use this material in any other 3D rendering software as well.
The material is seamlessly tileable and great for your realistic outdoor areas. The original footage was shot in Japan.
