Layer Blends and Splat Map Issue

Has the way layer blends work changed fundamentally in more recent engine versions? I have been following several tutorials for using splat maps to use color channels to define the heights of landscape layer blends in a landscape material. The issue is that the landscape only renders black in the editor. All these tutorials are a bit older, I assume something has changed in how landscape layer blend works, because if I use multiplies and adds to do the same thing I get expected results, but once I have anything to do with defining and using a landscape layer blend it renders the landscape as black in the editor. I have defined layer information sections for each layer defined, still nothing. One tutorial mentioned they were using 4.5. All the tutorials follow the same approach so something must have changed. Anyone have success using a splat map and could you show me an example where you also successfully defined landscape layers. I am particularly interested in using splatmap from World Machine to UE4.
