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.
