This started out with me wanting a backdrop in Unreal to place some water effects. It ended up with me messing in Unreal for hours and playing with volumetric lighting and lots and lots of foliage. I used only free assets from Unreal Engine, the Infinity Blade Grasslands assets, The Kite Demo, and some free Megascans library rocks. 

The water was done by me, which doesn't match because I had made it for a cartoonier scene I had scrapped a few months ago.

This is no where near done and I may never finish it. I really just wanted somewhere to experiment with waterfalls and beach water. I do have plans to turn the big monolithic floating rocks into magical teleporters.

A procedural tree experiment I did a little while ago using Houdini.

  

A work in progress creeper vine generator I've been working on using Unreal and Houdini Engine. I used this tutorial to learn how to create the initial houdini foliage and bake the texture maps: https://www.udemy.com/course/houdini-game-art-foliage/  Then I made the Houdini Digital Asset where multiple randomized meshes can be controlled with a curve in UE4.
