You can install Fx operators to the following locations:
• The SOFTIMAGE|XSI home directory under \Application\bin\ufos.
• The factory, users, or workgroup add-on directories under \Application\fx\ufos.
If an Fx operator is found in any of these directories, it will appear in the Fx Operator Selector section of the XSI Compositor’s interface.
