I'm trying a walkthrough-type animation of an architectural structure, and this
is my first animation using splines.
I have one spline that defines the camera path, one that defines the look_at
point, and on to use as a triggering spline where "flag" values indicate where
lights should go on, doors should open, etc.
The initial run-through works ok, in that the camera actually goes where I
intended it to, though the look-at direction doesn't behave as expected. No
surprises here, since I'm surprised run #1 has worked THIS well. ;)
I'd like some tips on controlling turns, and traveling forward and then back
along a cul-de-sac in the path. The camera seems to point backwards when I
thought I defined the look-at spline to be a point ahead on the camera spline.
I could also use a few tips on how best to handle going up and down staircases,
in terms of camera angle.
