First of all, props to WMCoolmon for adding the recent cutscene sexps. I think what we have now is a near-complete set of features for doing in-engine cutscenes, something I've personally wished for since the beginnings of the SCP. But as there's little documentation and/or discussion about them that I've been able to find, I'm confused about their usage.
Not sure if it's a bug ATM but right now the camera doesn't seem to rotate in a logical way when you point it towards objects, and, when it isn't moving or told specifically to point at some object with a turn time, then it resets its position to point straight forward, seemingly from (0,0,0). This can be worked around, sort of, by using an every-time sexp and a variable, but it's not ideal. I'm not sure if I'm using them right either as a couple of the sexps don't seem to match up their parameters with the ones in the description box - the subtitle one comes to mind. Ideally I'm sure most would prefer a persistent camera that does not reset when it's not in use... I can think of many great applications for it and am struggling to get to grips with it to make an intro to Inferno R2. Hope this prompts some discussion.
