I made this scene in UE4 to show off a HDA I made in Houdini for procedurally generating columnar basalt formations. I did everything myself except for the rain effects, which I got off the Unreal Engine marketplace. And you might have guessed the characters are just the UE4 mannequin with a bed sheet on.
The HDA and HIP file can be downloaded for free from here: https://app.gumroad.com/logpet
Feel free to modify and use in your own projects :)
