Charlie Wales (Carlos Rico Adega) posts another handy script that sets out to reveal all the hidden locations of Maya Icons. This new script is kind of inline with his last, which offered an easy method for finding which Maya Environment Variables are being listed and loaded.”
The Maya Icons script will show you the default Icon set, searching for icons then displaying them in a panel. You can also have this tool search all loaded symbols and not just those listed at hand-to-power!
A list of icons is shown in the panel. Each icon has its own name you can use for your scripts or Maya UI’s, and it also provides locations where they are found on local drive as well at various places online if necessary to find them again!
