  POV-Ray 3.6 Documentation Online View Edit Settings/Render Start Rendering (Go!)/Stop Rendering Select File and Render

This is the way to select a file from disk for immediate rendering. If the file is a POV file, it is rendered with the current options. If it is an INI file with no POV input file specified, the options will apply to the currently loaded POV file, only to be overridden by command-line settings. If the INI file specifies a POV input file, that POV scene is rendered with the options set in the INI file. See also Understanding File Types.
