Hi, can you clarify if you want to export individual Cinemachine vcams, or just the resulting camera controlled by the Cinemachine brain?
If it’s the latter, the FBX exporter now supports cameras and animation. It’s still in preview, but you can still install it with Package Manager as long as you don’t mind editing the package.manifest by hand: [#309]( New FBX Exporter in 2017.2 page-7#post-3561897)
There should be a demo video in that thread, too.
We don’t have any way to export individual Cinemachine vcams, although I suppose you could put a deactivated camera component onto every single vcam with a MonoBehaviour that sets its properties to be the same as the vcam. The exporter should then be able to export those cameras.
