First attempt at Geometry Nodes in Blender. Used Erindale tutorial in Blender to build a procedural hexagon world, then managed to add customizable trees on my own. A few parameters helps to change the hexagons' height, the erosion and the sea height. Then two empties let you change the texture and the hezagons' dimension.
Can't wait to explore Geometry Nodes more!
