Hi there,
I have been working a bit more on this scene, I have mainly been focusing on adding the distance plane. This goes around the terrain and will have some trees and grass on it, to create a sense of depth.
I have appended the distance trees geometry nodes setup from chapter 4 (Forest path scene final - Blender 3D environments course), and I also did use in chapter five. Since this scene is smaller than chapter 4 I adjusted the random value node, so that it spawns the trees smaller.
I used a vertex paint to control where the trees spawn, allowing me to stop them from spawning right along the edges.
I also applied the same terrain material to the distance plane, just without the blending.
Next up I will add the main trees to go on the main terrain.
