I'm probably not the best person to describe it since I just started out several
days ago, really new to the whole thing, but here goes:

I'm trying out the robot.mdl for testing with the IK and I can get a one-time
animation which has just a beginning point (frame zero, only the key button
pressed) and end point (last frame, key button goes yellow automatically after a
movement is performed on the robot model).  It works fine, no problems.
However, if I try to do two such movements on the robot model it breaks the
keyframing and will not interpolate the two sequences.  This is what I was
unsure was supposed to be able to be done or not anyhow, one sequence of
interpolations or if multiple ones were at all possible.
At best the motions get muffled down to a slight movement, as if the
interpolation were being scaled way down.

I think so if I understand right.  The reason for that was simply to do one
keyframing sequence at a time since it didn't work all together in one
animation.  I made it render each separate animation instead was what I was
doing to get around the problem of the model not switching from one motion
segment to another.
The held Shift key is something I didn't know about.

Not much to it to tell about.  I open the robot.mdl and press the Key button,
then I set the Options to have a certain number of frames, ie. 0 to 30.  I go
place the slider at 10 for example and move the robot arm into another position.
Move the slider to 20 and move the robot arm again and finally likewise a third
time.
Moving the slider from beginning to end to see the actions that will be done
only shows it to move from one position to another without any interpolating of
the movements.
I just saw a message posted tonight in which someone else at AOL has said the
official Moray 3.2 seemed to not have any bugs concerning this sort of thing but
I don't know exactly what was meant by that if the animation plugin isn't
updated as well.
Hopefully you could understand my explanations here, hate to make it tougher on
you than it already must be working with this stuff.  I was thrilled enough just
to see it in action, since after all Moray was able to do a IK animation but
like others I was trying to get multiple motions rendered out too and not able
too.  Still whether that is a bug or not is the whole reason for my question to
begin with.
Thanks for listening Alexander, anything more you want me to drone on about I'd
be more than willing.

Bob
