I have an attribute vop with a ramp. What I want to do is, as you know you can adjust ramps; typically with black and white values, although if you want color, anyhow.

When adjusting the black and white values, in my case do something to the geometry of the mesh, it is this change to the geometry which I want control within the material. Therefore when adjusting the slider for the geometry, the area would drive in materials a texture or color; although I don't know how to link the two together ?
