This is an environment that I did in UE4, I Created the whole foliage and props and everything you see there. (Water Shader is from Epic Games though
Prop Texturing was in Substance Painter and environment Textures were created in Substance Designer.
Foliage was created using 3ds max and Speedtree
Rocks and Woods done in 3Ds Max and Zbrush
Finally Rendered in UE4
