Add image based lighting with a preset or custom environment in the Material Viewer

You can add image based lighting to your render in the Hypershade Material Viewer. Choose from the provided preset HDRI environments or add your own. This feature allows you to see how your object reflects and refracts in different environments.

Add image based lighting to your Material Viewer render

Select any of the options from the preset environment drop-down list.

For each preset, a color and a neutral option are provided. The two have the same intensity, but the neutral option is without color so that the environment does not influence the shading of your object.

Note: The preset environment options may or may not be supported by 3rd party plug-in renderers and the Hardware renderer (Maya Viewport 2.0 renderer). As such, there may be no visual change when selecting between different environment options. Currently the mental ray renderer supports this option.

To disable the image based lighting environment

Select Off from the preset environment drop-down list.

Add a new custom environment

1. From the preset environment drop-down list, select Add New.

   The Custom Environments window appears.

2. Click Add.

   Enter a name for your custom environment and navigate to its path in the Image File field.

Obtaining .exr images of the preset HDRI environments

You can find .exr images of the provided preset environments in the \presets\Assets\IBL folder of your Maya installation. It is recommended that you copy these files to a different location in your network before using them as IBL images. Do not overwrite these images in their installation directory; otherwise, your IBL presets in the Material Viewer will not work as expected.
