I did a couple of tests and I noticed something that appeared very strange at first, but makes sense:
if you give an animated camera to a node in a DLG file that:
has no "Camera Field of View" entry as visible in Kotor Tool's Conversation Editor,
the previous node uses a placeable camera,
then the animated camera adopts the angle of view of the placeable camera (that was used in the previous node).
It's a very hacky way of setting a view angle and I don't know if this will ever be useful to anyone, but, just in case, I'm putting it out there.
