UE4 Vertex Painting

I love the UE4 material editor. I have been messing around with it for awhile now. I learned more about vertex painting from a tutorial by Aaron Kaminer. I combined his way with a material I have been working on but he taught me how to be more efficient with the vertex colors so, that I am able to blend more materials with just 1 vertex color. I made my material modular for textures that may or may not have rgb masks. I plan on pushing it further but this is what I have so far. I really enjoy playing with the material editor.
