#Cycle object prob.
9 messages in this thread
Hi Guys,
OK I gota question for ya. I have created a model of a book. The model
contains the folowing objects, A cover that is joined with a font object, a
back cover, a block in the middle to simmulate pages and a binding. I want the
front cover to open up during the animation. I brought the object into the
cycle editor and made one key cell with the cover closed and anouther key cell
with it opened. If I make the animation in the cycle editor it works fine. The
cover opens away from the book. When I bring it into the stage editor and make
the animation the book opens away from the cover and down into the table it is
sitting on. What am I doing wrong here???

Have you tried using STATES instead of the Cycles ed?
Hi Peter,
Hmmmm states?? now thats an idea I havent tried yet but now that I think
about it it just might work.
Thanks for the
reply,
Mik
Glad to help, hope STATES does the trick for ya. Since States was
implemented I have essentially given up on Cycle Model Making
Hi Peter,
Well States did work…. once I figured out how to get it to change from one
state to anouther :-). A few more key frames to get the camera moving right
and I will be ready to sit back and let the rendering begin. I am going to be
siting back for awhile on this one.
Thanks
again,

Glad States worked for you. Be nice if eventually we can use States like
Cycle Objects by simply saying ok use State 1 ,2 5 and 7 and make it a
20 Frame loop and continue looping as long as "ACTOR" is present in that
timeline……So a 300 Frame Anim would have the STATE anim Loop 15
times…..

Well with any luck the folks a Impulse are taking notes 🙂 and we might
see this in the future.(hint …hint) All in all though I am EXTREAMLY
HAPPY!!!! with Imagine. I was all ready to spend months on a learning curve
before I would ever be able to produce anything (since I am new to 3D) boy has
Imagine proved me wrong 🙂
BTW Peter, just out of curiosity what are you using Imagine for??? As you
can tell by the tag line on my messages I own a video production co. and thats
what I use it for.

Michael,
I have a hunch that you've encountered the 180-degree problem. Imagine is a
keyframe-based program: set the start values, set the end values, and let
Imagine calculate all the in-betweens. If your start value is a rotation of 0
degrees, and the end value is 180 degrees, you have a problem. You see, 180
degrees and -180 degrees lead you to the same final position; given that
position, how is Imagine supposed to decide whether you wanted to go from 0 to
180 by moving through positive values, or 0 to -180 by moving through negative
values? The answer: Imagine can't. It'll make its best guess, which can change
depending on the circumstances of the moment. Sometimes Imagine will go from 0
to 180, other times from 0 to -180.
Imagine users should always be unambiguous when specifying keyframes. For
example, in your final keyframe, rotate the book cover 179 degrees rather than
180 — nobody will ever see the difference.
Another situation where this occurs is when you want to rotate an object 360
degrees. The final keyframe, at 360 degrees, is interpreted as 0 degrees, so
Imagine will tween from 0 to 0, and your object will not rotate. If you use 3
keyframes (start, midpoint, end) and set them to 0, 180, and 360 degrees, the
values are ambiguous and Imagine will probably rotate your object in a
ping-pong manner, rather than a full revolution. The solution here would be to
have 4 keyframes (start, 1/3, 2/3, end) and set rotation angles at 0, 120 , 240
(or -120, same thing), and 360 (or 0, same thing) degrees.
Blaq!
Hi Charles,
Thanks for the reply. I have ran into this problemn before and so this time
the rotation was right. Hmmm…. I quess I will just have to kep pluging away.
I have tried both pivoting the links in the cycle ediotir and loading poses
form the detail editor and still get the same result 🙁
