With this tool you can easily create paths for cameras to follow.
You have the ability to place waypoints at the position/rotation of the sceneview camera and manipulate the path between them using beziér handles directly in the editor. Of course, if you need precise control over the playcement, you can change the raw transform values of every waypoint.
You are also able to change the visual style and tranform manipulating mode of your path in the editor - whatever is easiest for you to use!
The integrated path playback panel is an easy way to test the path and by scrubbing through the timeline you can easily find any errors.
