1. Is there a way to set a target for the camera so it always points at the target object?
2. Is it possible to get a card (billboard) to always point at the camera?
Unfortunately the answer to both is no, but it is a capability we plan to add in the future.
I should say that if you do your targeted camera animation in another app and export it via FBX then TG3 can import it and match that movement.
