Hi, I’ve been trying to make an Automatic Landscape Material that changes what material is used depending on the slope. When I just use the material’s Albedo, Specular, Metallic and Roughness, everything works as expected. However, upon connecting the Normal node, the materials seem to invert and the effect of the blend is altered completely. I have totally no clue as to what may be causing this issue or how to fix it. Thanks in advance! 
Parameters used as inputs to change material used in Material Function and then broken into Material Attributes
Normal Node not connected into MakeMaterialAttributes
Texture appears on both sides as desired (I know my materials are switched around) (Normal Node NOT connected)
Normal Node connected into MakeMaterialAttributes
Texture appears only on one side, however, the materials are in the right place, i.e. grass is at the top (Normal Node connected)
