Materials in Iray for 3ds Max are integrated directly in the 3ds Max Slate and Compact Material Editors, with a large, high quality library of example materials to give you a reference point to create virtually any material. If you prefer to start from scratch, Iray+ base components give total freedom over building materials.
Iray in the Material Editor
When you use or create a new Iray+ material, you have the ability to add optional Decal, Coating or Surface Layers to the Base and Geometry layers. You add these in the Material Detail panel in any combination or number.
Each component can be moved up, down or deleted using the available Up, Down, Delete buttons.
The quickest way to get started with materials in Iray for 3ds Max is by choosing an example from our supplied material library. You can then adapt this to your own requirements. For this example we will take a material from the example Iray+ Material Library.
If the LwIrayPlusMaterials.mat library is not loaded in the 3ds Max Material Editor, click the dropdown arrow at the top of the Material/Map Browser and choose Open Material Library...
Navigate to C:\Program Files\Autodesk\3dsMax2015\materiallibraries* and choose the LwIrayPlusMaterials.mat file
Inside are several example materials to use and adapt.
In this example we will work with an Iray+ Material component to create a complex multi-layered car paint.
Create a simple studio environment and add a 10m³ object such as a ChamferBox
Apply a UVW map modifier and set Box as the mapping type
Open an ActiveShade window to view the changes to materials as you add layers
In the 3ds Max Material Editor, choose Iray+ Material from the Material/Map Browser from Materials > Iray+ > Iray+ Material and apply this to the object you created. Select the following parameters to create the basis of the material:
Base Preset: Matte
Colour: RGB 0, 35, 4
To add some paint flakes, add a coating layer from Iray+ Material > Coating and apply the following parameters:
Coating Preset: Flakes
FlakeColour: RGB 124, 251, 0
For a second coating layer, add some finish to the material. Add a coating layer from Iray+ Material > Coating and apply the following parameters:
Coating Preset: ClearCoat (remove the Iray+ Perlin Noise map attached to the Normal parameter)
DiffuseColour: RGB 7, 10, 28
ReflectedColour: RGB 255, 255, 255
Now add a Surface layer from Iray+ Material > Surface and apply the RadialScratches2 preset. You should have a material similar to the illustration above.
