Marching Cubes? Blueprints? How can I make this?

Hello, I am new to Unreal Engine and trying to create a world similar to the one in this video:

I’m not sure if marching cubes is the algorithm used here, but for the life of me I can’t find any tutorials on implementing the Marching Cubes algorithm. I there a way to do this through Blueprints? I am hesitant to learn C++.

Does this inquire I can use the free version of this plugin?
