How do you map a vertex's UVs in a material?

I have set 2 uvs per vertex on my mesh and I’m curious how I can use them as inputs on a texture’s UVs in a material?

Did you try a TextureCoordinate node?

Video tutorial

Yup texturecoordinate node will allow you to switch to the different UV layout (usually either 0 or 1 unless you have more). Plug straight into the texture node.

I keep on forgetting about the youtube channel. Thanks!
