3rd Party Render Support

I searched this forum for answers but I could not find any. Does anyone know if there are any 3rd party developers that offer a render solution for Fusion? Something like Arnold or Octane? I know.. I'm new to this forum and it is always customary to do a search first. I did not find a suitable answer. Thanks

Well I kind of figured it out.

Right now there is now 3rd party render available for fusion

The plugin API of fusion can be used to create external render support (in the sdk of the older versions there was an example for a renderman connection which I used to build a 3delight plugin)
If enough people show a demand for a specific renderer the the company of this renderer can produce a plugin for fusion
