At this time, third party plug-ins are not officially supported or tested in the Ozone or RX applications.
Many VST and AU plug-ins will scan in and work normally but it is not uncommon for some to cause unexpected behavior.
Plug-ins by Waves are not compatible in the standalone applications offered by Ozone and RX. In most cases, the plug-ins will not scan in or may result in unusual behavior when attempting to use them in the app.
All iZotope and Exponential Audio plug-ins will load and run inside of the RX and Ozone applications.
