You can customize all predefined lighting setups (except Headlight) in the Creo Illustrate user interface or by editing the LightScenes.xml file. The file is located in the following location:

Customizing through the user interface is simple and limited. Editing the XML file is more complex, but gives you more flexibility, including the ability to add lighting setups. Information about using the Creo Illustrate client follows. For information about editing the XML file, see the section “About Editing the LightScenes.xml File” below.

The settings for lighting are saved with the figure. You can customize and save one lighting setup per figure.

Custom light settings are retained in published figures and saved to 2D raster image formats. They are also retained in exported 3D file formats that display surface shading.

In the Creo Illustrate user interface, you can customize predefined lighting setups.

You can change the Ambient, Specular, and Diffuse settings for the selected lighting setup.

Your custom lighting setup is saved with the current figure. Each figure in the file can have a different custom lighting setup.

Edit markup in LightScenes.xml to change settings for the three predefined light setups:

(The settings for Headlight are not encoded in the XML file.) When you save the XML file, the settings in it become the new predefined light setups. Then, you can customize the setups in the user interface as described above.
