What would be the best way to get an array of random coordinates from a seed?

Hello, i’m developing a procedural environment creator in Unreal 4.18 using blueprints, i’ve figured out most of it, like, how to create procedural terrain, with LOD levels and all of that. But, i can’t seem to figure out a way to get an array of random coordinates given a seed, a limit to the array and a radius for the coords to lie within.

So, does anyone know of a way to do this?

Thanks in advance.
