The procedural terrain is driven by one grey scale 16-bit picture, 4096*4096 pix, by sampling the picture, recalculate and shade in different ways, eventually get a height data of the terrain to generate meshes, apply with generated shaders and directional light to get a beautiful render output.
Also the picture can be painted anytime, the mesh and render are changed in the same time as artist paint it.
All finished in blender, rendered by Eevee. Used for company engine game development. The mesh can be generated into different LOD, it’s ready for game.
