But whenever I check the option 'TRUE' the mesh looks all like plastic, or metallic. I'm not very sure why, I have looked a lot of places and options but can't really…

   One thing I notice is that you have your roughness set up as glossyness so you're using a 1minus node to get it back to the correct range when you're not using vertex colors. (also this will break and give likely unexpected results if your "glossyness" multiplier ever goes over 1, as it will result in negative values for…
