I made this environment from a map created in gaea, I then created 4 trees in speedtree from a single photo (I made the map opacity and the normal in Photoshop) I integrated the whole thing in unreal engine 5.1 where I entirely generated the vegetation in a procedural system / I then did the lighting without any plugin, just the post process volume / I used nanite for the vegetation and lumen for it global lighting, sorry for the video a bit of flickering to fix... otherwise unrela engine 5.1 is amazing!!! /// :)
