Landscape Unreal Engine 5 / AutoMaterial & Paint

I made this map by creating a material with the auto-material system under Unreal Engine 5.3.2 / I then integrated into this shader the possibility of painting different textures, I then used a 4k heightmap to finally integrate vegetatin that I made in speedtree as well as elements of quixel megascans, I also finalized the whole by creating lighting using the post process volume and without any plug-in / I will used this map to show all of these elements during a course that I give at the Edaic school in Lyon, France. /// :)
