A beautiful nature scene of a forest with a river going down the middle.
Please note that the number of trees will be limited in the viewport by 1/10 for performance reasons. Also the trees use Proxies to improve the viewport responsiveness and the actual tree models will be shown in the final render.
The main foreground terrain and the background mountains were created in Gaea and textured in Blender.
The volumetric clouds were created using a Geometry nodes cloud generation setup I created.
