A smaller environment built with the Alien Jungle pack and UE4.24's SunSky plugin. I tried out a different color set with the plants material instance values too.
That Unreal pack is here: https://www.unrealengine.com/marketplace/en-US/product/alien-jungle-set

The assets themselves were made with a mix of Maya, Houdini and Substance Designer.

The set is also up for Unity: https://www.assetstore.unity3d.com/#!/content/162908

Substance materials are also available: https://undertow.artstation.com/store
