Here’s a couple of ways to open a URL in a web browser from inside Softimage. Unfortunately, these worked on Windows only. On Linux, the JScript can’t create that ActiveX object, and the Python didn’t do anything.

JScript:

// Open a web page in the default browser
var objShell = new ActiveXObject("shell.application");
objShell.ShellExecute("http://support.solidangle.com", "", "", "open", 1);

Python:

import webbrowser
webbrowser.open( 'http://support.solidangle.com' )
