I will start by saying I am NOT a material expert in anyway so this is all on me, meaning, my ignorance is creating this issue. I am wanting to take two full materials that are each a type of aged plaster wall. In order to break up the texture tiling using just one material, I want to be able to control the blend of 2 separate materials using a mask. I do not want to do vertex painting/ blending since it would mean I am adding more vertices/ faces to all of the walls. If I can take two materials, control the UV tiling of each separately as well as the mask, I should be able to get what I want…I think. I’ve tried this with what I am showing here but the preview, and resulting material instance, show just this solid color.

I figured out the problem. Themateriallayerblend node was not working with the layer attributes. I used the blendmaterialattributes node whcih took care of things. There is just so much I do not know or understand when it comes to materials. It is like spending time in an inlet thinking you now know the nature of the ocean.
the layer blend nodes are specific to layered materials - this stuff is not well documented at all so don't feel bad
