Project from view UVs

I have a model containing 2 “UV from projection” UV maps along with . I have two two different texture layers. When toggling thru the layers in the Texture tab, the respective images appear properly. But when I toggle thru the same layers in the Material tab only the bottom layer image appears. Both have their respective Map Input UV names as well.

Can I not have multiple UVs created from “Project from View”?

I believe I solved one problem.

After creating a Project from View UV, you have to isolate the polys on the model, then move them to one side in within the UV window.

But I still don’t understand why only the UV listed at the bottom of the texture list is the only one rendered.
