I need help for terrain generation in runtime

Hello everyone, I’m french so please don’t say to me that I have bad english.
I have made blueprint scripts that works like voxels: they save all the spawned actors, destroy them when they are too far away and reload them when they’re near.
But I have one issue: I don’t know how to generate the world when starting the game.
I tried making a heightmap with the noise node in materials (generating the 2D texture with the 2D scene capture component) but I’m not able to get the values of each pixel in blueprints, so it’s pretty much a failure.
I don’t have any knowledge of C++ but I think i have a good knowledge of ue4.
Can someone help me?

Ok nevermind i created my own terrain generation algorythm

Since you created world generation, can you teach me how to do it?
