    Default vMaterial Controls

    Each of the vMaterials has a set of controls which adjust the various parameters that are relevant to the material. Each application will show the controls in a slightly different way, but the changes to material will be the same. All the controls will be grouped by which part of the material they affect. Most of the applications will provide more information on any parameter when the mouse if hovered over the parameter.

    Here's how Iray for Rhino shows the controls for Brushed Anodized Aluminum in the Design catalog:

    This section will include controls for color, texture maps, surface roughness, or the strength of material specific parameters. In this particular material the controls would adjust
    • Aluminium Color: The color of the Aluminum metal which will get blended with the anodizing coat
    • Coat Color: The color of anodizing coating.
    • Reflection Weight: How reflective or shiny the surface will be, higher numbers are more reflective.
    • Reflection Roughness: Controls what the reflection looks like, a rougher reflection will spread out more across the surface
    • Brush Strength: Defines the how strong the brush appears. A larger number will be a deeper or stronger look.

    Controls here help place the material's texture onto the model's UV maps. In general vMaterials with two transform or scale parameters are using the models UV maps, where ones with three values are using object space procedurals. This material has only two so it's using UV Maps
    • Texture Translate: Moves the texture in the U and V directions
    • Texture Rotate: Rotates the texture around the origin in the specified number of degrees
    • Texture Scale: Multiple the size of the texture by the values entered in the U and V directions. Larger numbers will increase the size of the surface textures

    Parameters here are ones that most people are not going to need to adjust, but they are present to help get just the right material behavior.
    • Aluminum IOR: The Index of Refraction for the Aluminum. The default value here is the correct IOR for Aluminum
    • Coat IOR: The Index of Refraction for the anodizing coat
    • UV Space Index: For applications that support multiple UV mappings per object, this specifies which to use. Iray will only use the first 5 UV spaces that are defined in your application if it supports more.
