Material Editor help

I’m trying to make a new material with 3 layers for painting my terrain but it seems that everytime i use this guy’s layout it don’t work.A black sphere appers and i am now to UE4 and don’t know what else to do.Did saying change with latest update or is this just plain wrong.If you have a better layout (doesnt matter what you made just need an example so i can get started) i would love to use it for help creating my materials.

Post a screenshot of your material graph and I think I can help you out.
