I did this environment for learn a bit of Unreal Engine, I'm surprised how powerful and fast for delivering good image quality, so I started to scattering foliage over the basic terrain Unreal offer then I modified it a bit creating some mountains in the background and then select a good spot view for place some abandoned old house and framing a composition to finally place a hero asset I did on the software Speed Tree for close the final composition, I really enjoyed doing this, I hope you like it, thanks!
