Is Splat map not working in ue4 anymore?
This is shader
This is the result
Did you ever find what the problem was? I’m getting the same result today and it’s driving me insane 
The problem is you don’t seem to have painted any layer…
I am having the same problem. The splat map is used as a mask so you aren’t suppose to hand paint.
Wrong. You need all layers painted to get the desired effect based on the shader code shared above.
