Returns metadata from one of the 4 input COPs connected to the VEX COP. Use the nodes parameters to set up the material look. Houdini then compiles the node network into executable VEX code. Component models are roughly equivalent to Geometry Objects in Houdini. It looks like you're using ArtStation from Great Britain. The material knows which shader types the network implements by inspecting the context type for the Output VOPs. I. Its optional for material nodes to have a layer output to allow mixing.
