This feature is still in development. As time passes, more and more plugins will be supported.
OpenFX support in Turbo Play is very good. Most "image effects" work, for example you can try The Misc plugins (https://github.com/NatronGitHub/openfx-misc
). Turbo Play includes some of the Tuttle plugins (https://sites.google.com/site/tuttleofx/
). OpenFX is still in development, if your plugins do not work with Turbo Play, contact us and we will setup a remote debugging session.
