#Smooth Moves
8 messages in this thread
Okay, help me out. If I put together a nice smooth camera move, say from a
high position moving to a close-up, and add a full ease at the end,
everything's fine. A nice linear move. NOW, if I add a keyframe somewhere
along that linear path, say to pull the path into an arc, suddenly my spacing
along that line changes! What can I do about this? I have figured out a fix
(using a camera parented to a dummy), but is there a different solution?
Thanks.
Save your file, then try the smooth option in the keyframe dialog box for
your camera tracks. This will evenly space the keys (with no undo). Push OK,
then see if your middle camera keyframe position is where you want it. You
might have to tweak some. When happy, choose key info for your last camera
key, and set your TCB to the values you want. Hope this helps.
Paul S,
Well, you see the problem is I DON'T want evenly spaced camera positions,
since I have an ease in on the final position. What I don't understand is why
the spacing changes when a key frame is added. I might add that this doesn't
seem to happen if no ease-ins or outs are used. Thanks.
Hi Glenn,

Now I understand.. You are trying to control the acceleration/deacceleration of
an object through keyframes. There is an IPAS tool to help you do this.

Keys: YOST GROUP IPAS3 TEMPO KXP VELOCITY MOTION EDITOR DEMO
This file contains a working version of Tempo kxp, but cannot write keyframes
back
out to the Keyframer. Tempo is a velocity motion editor for position and
rotation
tracks, allowing you to draw motion curves for objects using bezier splines,
apply
constant velocity or acceleration, fractalize motion, and do previews in real
time.

Jonas, PMJI, but while you're on the subject of Tempo – I've got one for ya.
The other day I was using the constant velocity function between two keys which
worked fine. But, it changed some of my other keys continuity values that were
not included in the range of frames I gave tempo. ANy ideas? It was simple to
fix but weird anyways.

I would need a reproducible case to examine. If you can provide me with one,
I'd like to see it.

Okay, I'll check the Tempo demo out. But I'm surprised to hear that it
takes an ipas routine to fix something like this. Thanks.
If you have release 4, have you looked at the pathman.k3d script that
comes with 3ds? It will do path smoothing, acceleration, and
deceleration.
