Is it possible to add 2 or more cameras and keyframe the active one? Or would I have to render both animations and then fix them in post?
BTW awesome course! Loving it so far! <3
Yes you can change the active camera. There's a new course coming next month that explains everything like that, but just select the camera, then in the timeline (on the frame you want to switch) press CTRL B.
(Bind Camera)
This will create a camera marker that will switch cameras. You can even drag it around to change the frame of the switch.
