I Displacement it Using Geometry nodes in Blender My Blend File is Also Included. With a Screenshot of node trees in geo and shader node with explanation. My displacement node Group (Which is Included) Is super easy to use and has many Controls. Including a Subtraction, which I used for lowering the Height of Foliage in My "Displacement with fake Foliage" Map.
all textures are in 4097x4097 resolution, which is desired for Unreal Engine 5.
you can make terrain upto 4x4 to 10x10 Km, but 5x5 KM is default. using different scale might spawn some weird spots on Landscape, but those spots can easily be fixed by smooth brush in Landscape editor.
Default Scale is 5x5Km width and Length and 2.6km height. But You can Make it up 10x10KM without any issue and more.
