Just roaming around in the Birch Forest Biome example map for a few minutes. Everything you see was procedurally generated with within 30 seconds. There is 4 square kilometer of insanely detailed forest to explore. All custom photo-scanned assets. This is running in Unreal Engine 4.26 with fully dynamic lighting at Epic settings on a RTX 3080 Ti.
