Rendering with mental ray and 3ds Max probably learn to create Arch & Design materials for the added flex- ibility and efficiency. Because ProMaterials has so many preset parameters and so few user- customizable options, there is a good chance that when you go into a presentation, your scenes will look very much like those of your competitors and you will have lost some of the originality that may help you win the bid. In some cases ProMaterials have a tendency to render slower than Arch & Design materials that would otherwise appear similar in a scene. Let's look at some typical ProMaterials and then look at the imported FBX file from previous exercises to see how those materials have been applied in some of the options for which you might have to make adjustments. 7.3.1 ProMaterialtype There are libraries of materials that shipped with 3ds Max which include the ProMaterial type; they are listed according to categories of typical archi- tectural materials such as con- crete, glass, or metals, for example. In the next exercise, you will open a couple of basic ProMaterials to see some of the parameters that are avail- able in the Material Editor. Figure 7.9 Use the Material/Map Browser in the Material Editor to view a list of the materialscurrentlyinthescene. 7.3.1.1 Exercise:Alook atProMaterials 1. Open 3ds Max and then open the Material Editor. Figure 7.10 Clone the materials in the scene to the Material Editor so that they may be editedandaccessedfromotherscenes. Click the Get Material button below left of the sample window and make sure that, in the Material/Map Browser, the New radio button is set in the Browse From area. In the list of available materials, you will see a listing of available ProMaterials (see Figure 7.11). 2. In the Material/Map Browser, double-click on ProMaterials: Ceramic to load it into the first sample window. In the Ceramic Material Parameters rollout, the first option you'll see is Type with a drop-down list. Click 220
