XNA: Retrieve texture file name during runtime

Question

I'm trying to retrieve the names of the texture files (or their locations) on a mesh.

I realize that the texture file name information is not preserved when the model is loaded.

I've been doing tons of searching and some experimenting but I've been met with no luck. I've gathered that I need to extended the content pipeline and store the file location in somewhere like ModelMeshPart.Tag.

My problem is, even when I'm trying to make my own custom processor, I still can't figure out where the texture file name is. :(

Any thoughts? Thanks!

UPDATE:

Okay, so I found something kind of promising. NodeContent.Identity.SourceFilename, only that returns the location of my .X model. When I go down the node tree he is always null. Then there's the ContentItem.Name property. It seems to have names of my mesh, but not my actual texture file names. :(

Alright, I think I figured it out. Maybe not the best solution (so I would still appreciate other answers ;) )

public override ModelContent Process(NodeContent input, ContentProcessorContext context)
{
    ModelContent model = base.Process(input, context);
    foreach(ModelMeshContent modelMesh in model.Meshes)
    {
        foreach(ModelMeshPartContent meshPart in modelMesh.MeshParts)
        {
            MaterialContent materialContent = meshPart.Material;

            foreach(var texture in materialContent.Textures)
            {
                if(texture.Value != null)
                    meshPart.Tag = texture.Value.Filename;
            }
        }
    }
    return model;
}

The Tag property of my ModelMeshPart the file points to the .xnb file in the output directory.
