Hiya Mike, looks like you're using the "webview" of the newsgroups. I don't
use it much, except to search for things there occasionally, but there's a
Post a Reply to this Message (Beta Testing) link at the bottom of each
posted message which I'd guess is supposed to do like it says. :)

I see that your camera look_at spline is going to need at least 3 points
when using quadratic_spline, 4 if were cubic_spline instead, because each
preceeding point is a control for the next. The following two points get
plotted (inbetween first and last if cubic used) on the spline path
according to that previous point.

For those skeleton parts you used only a single point at value 9, so that
would only be plotted at clock=9 (and I believe <0,0,0> at other clock
values in this case). You'll need to add more points in.

Hope that clears things up.

Bob H.
