Hey there! If you want to do a procedural terrain, you should look into the runtime mesh component plugin and meshing techniques such as Delaunay triangulation.
It would look something like:
- Get some 2D perlin noise (unreal has a built-in function for that)
- Get the value of the perlin noise at regular (X,Y) intervals and use that as the height of the point You should now have an array of many 3d points
- Make it a mesh using a Delaunay triangulation
