Multiple UVs in Procedural Mesh

I’m totally new to creating procedural meshes. I’ve created a set of custom meshes using Procedural Mesh. A few of them need kind of like a blended sort of view. I have 2 UV maps for 2 different materials and alpha values for blending. I need to put them together. How do I apply 2 UV maps onto my mesh? How to proceed further with Applying the materials. I’m completely confused.
