Hello! Thanks for the responses!

I am not sure if the textures are actually plugged in the shader. As i mentioned, I'm quite new using maya. I can tell you guys that the file that i downloaded has two documents, one says "Arroway_Concrete-46.ma" and the other says "Arroway_Concrete-46.ma.swatch". When i import the first one it appears in my materials tab in the Hypershade window. I have attached an image of what appears in my work area when i graph this material, what i believe to be the network and node connections (correct me if I'm wrong).

I also have attached an image of the textures file that i downloaded separately from the material one. I know for sure that these textures are specifically for this material.

I don't know what you mean with "material swatches may have been baked". Sorry for being kind of clumsy, I have just started using Maya.

Thanks!
