Octane for Houdini

The OUT Material node creates the top-level material node in an Octane VOP network and is required in order for materials to apply properly to scene assets.. OctaneRender® creates this node by default when you create an Octane VOP Network node using the Octane Material Builder node at the MAT level. Additionally, this node provides the option to create more than one OUT Material node within an Octane VOP network, which allows for more than one material to be contained in an Octane VOP network (figure 1). These Out Material nodes can then be mapped to different scene assets in the OBJ network view (figure 2).
