For months have been learning how to create an environment using the skills that I've learned in multiple 3D software.
With the help of the course "Ultimate Environment Course" by Micheal Gerard, I have managed to create something amazing and learn a lot more than I could ever thought possible in Unreal Engine.
Vegetation is created in speedtree, textures comes from megascans library.
Ruine assets are from the megascans store.
Mountains were created in Gaea and then Fixed in blender.
Environment created and rendered in Unreal Engine.
