Lighting setups in the Creo ViewLights list are encoded the Light Scenes XML document. Creo View uses the Light Scenes XML document stored in this XML text file:%APPDATA%\ptc\ProductView\LightScenes.xml.

You can edit this file to change or delete lighting setups in the Lighting Setup list. (To open the list in Creo View, click the ribbon Figure tab, and then click the Lighting Setup box in the Lights group.) Lighting setups include properties for light type, color, and direction. To update the Lighting Setup list after you edit the XML file, place a copy of the updated file in %APPDATA%\ptc\ProductView\LightScenes.xmland then restart Creo View.
