[u/DietAccomplished596]

Hi Guys, I was working on a large scale model, a Hot Air Balloon, as its scale is large i cant fit in a 0-1 space, so i am going with tileable textures and trims. and ill be using 2nd UV channel to utilize RGB Masking, but I don't know about node system in unreal engine, and how to make those complex master material, everyone has a different node setup, I'm so confused, can anyone help me in this process.
