Hi there,
This will move smoothly and steady along spline for given duration. If you need to look camera to something you can basically use find look at rotation on tick, or use cinecamera to focus.
Tangent have nothing to do with camera when you arrange it that way its just spline tangent.
Another approach is to use some scene components to dynamically create a spline and you can auto arrange curves etc.
Another more nicer approach if you are going to use in dynamic environments like in quest etc. Which needs to fit in a bigger system with more complex setup and constraints, you can use ai to find path and generate spline on top, which is way more nicer approach and causes less pain with tangents etc, that you having.
