Trying to have a layered texture to paint, but always appears black in my world

For some reason my texture is always black in my world and I don’t know how to fix it.
Check these two links for the pictures:

One picture shows my texture in the world, the other shows the blueprint for the texture.
I am new to UE, so any help would be appreciated!

I think you can use that node only with landscapes (I might be wrong though). Try this instead and see if it helps !

what about something like this video: this is what im trying to do.
Did the algorithm change since the video was uploaded?
