This node holds all the material properties and Layer connections. It is the equivalent of the "Material Properties" in the MXM (Maxwell material format). Here you can change Global Bump textures, global texture tiling, activate dispersion or shadows for the material etc. From this node you can also click Add Layer to add a new Layer node to the material. The Maxwell Layered Material must always be connected to the Surface output of the Softimage Material node. For more information about these parameters, see the Global Material Properties page in the Maxwell documentation.
Maxwell Layer
This node describes a Layer in the MXM, which can hold several BSDFs and Emitter components. Effectively, each Layer is a material in itself, which can be blended together using Layer masks.
To add a Layer to the material, double-click the Maxwell Layered Material node and click the "Add Layer" button. The order in which Layers are connected matters - a Layer above another Layer will hide the Layer underneath it, unless it is set to Additive mode or you are using a Layer mask. Please see the Maxwell Materials section for more details on working with Layers and more specifically the Stacking Layers page. Due to an SI SDK limitation it is not possible to automatically create a new port when trying to connect a Maxwell Layer node into the MaxwellLayeredMaterial node. You have to add an new port via the "Add Layer" button in the MaxwellLayeredMaterial PPG.
