A work-in-progress script of mine.....with video examples :D

07 Oct 2006Hey peeps,
No script posting yet since it's still a teeny bit buggy (mainly when it comes to major orientation changes in the objects), but here are 2 demonstrational vids I made for a script I've been working on......
It's a script that automatically generates secondary motion for objects in real time.....
Basically, it allows objects to extrapolate angular motion from other objects to create the illusion of realistic secondary motion. All settings are customizable, and the script updates 100% in realtime in the viewport, and dynamically reacts to keyframe changes you make on the fly. It's actually a really simple setup......but the script helps to optimize and automate the creation process.
Check em out!

07 Oct 2006Ah what the heck....it'll be hard to get feedback if I withhold the script so here it is in it's current form
I guess you could say that it's version 0.1
If you do try it out....please feel free to post your feedback/comments/issues/errors.......it would be nice to make this script fully production ready, since I can think of about a trillion places where it'd come in handy. -
07 Oct 2006Mate that is friggin awesome!
You've outdone even yourself with this one, absolutely insane. -
07 Oct 2006I'll probably add these notes/things as I go but here are a couple of cool things that are in the script:
-each object that recieves the secondary motion attribute is also given custom attributes which can control the weight/timing of the motion. The custom attributes are available in the modifier panel for each respective object, that way you don't have to run the UI script every time you want to adjust those things (although the UI script will make it slightly easier with the batch override command)
-let's say you have a chain of 8 bones/boxes/whatever that you applied the script to (and let's also say that they're all part of the same chain)......if you want to break off the last 4 bones/boxes in that chain and attach them to something else, simply link the black point helper of the 1st bone in that group of 4 to something else (the same way you'd do any kind of FK re-linking), and the secondary motion of those bones will automatically be derived from the new parent object to those 4 bones.
-MAKE SURE that you align the pivots of your objects TO THE WORLD *before* running the script on them! If you don't the objects probably won't rotate on the right axis, and they'll also jump out of place. -
07 Oct 2006one word to describe this script
this is script is just
T (I need to make an icon for this new word, something like a foot holding a computer mouse) -
07 Oct 2006genius. i'm honored to have been here to see it happen.
but i think the best part might be what this implies - you're a very busy guy, and i can't imagine you'd just stop what you're doing and write this. I believe this has something to do with your Creep short, or maybe some other short you're working on, like those guys around the cake. I think this is a tiny part of some grander project, and THAT is friggin' exciting!
but, i could be totally wrong, and maybe you just had a good idea and this only took you ten minutes.
either way, thanks a million! i'll never animate secondary motion again! -
07 Oct 2006Hahah you got it hype....although it's not quite as exciting as you've imagined....we're doing a spot here at work that requires raindeer pulling santa's sleigh......and I didn't want to animate the sleigh and then have to manually do some guesswork when it comes to the pulling motion of the reigndeer......so I wrote this script to do it for me.
I didn't show it in the video because I only showed what a negative frame offset looks like, but if you change the negative offset number to a positive, the tentacles/tails/whatever will rotate inversely to the way they would when they're being treated with secondary motion. When the offset is positive, it gives the illusion that the top-level parent (in the cases of the videos, the sphere) is receieving the secondary motion, and as we travel down the chain we get closer to the end bone which appears to be generating the primary motion.
Coles-notes/de-jargonized version: If we change the offset to a positive, instead of looking like the main, rotating object is affecting the child objects through secondary motion....it instead looks like the main object is the one recieving the secondary motion as it's being "pulled" around by the child objects (ie.....santa's sleigh being pulled by reindeer)
Haha....wow that was a mouthful for something so simple
I suck at words.
Here are two quick playblasts showing what I mean:

07 Oct 2006Simply amazing.
Love the video's! -

08 Oct 2006hey man! this is what i suggested in the tutorial requests thread you made.
simply AMAZAZING! -
08 Oct 2006wow. nice work t , i cant wait to load this up in max and disect it ! . i think we should have a few small challenges/workshops that focus on scripting because i really want to get cracking on it. although i guess we would have to make it application specific :S . its just a thought though . i guess having walkthroughs would be best that way you can apply the same logic to other applications .

08 Oct 2006oh and thanks for releasing it ! .

08 Oct 2006Nice one T. Just had a quick look at it in Notepad, (Max script is not so easy to read, though I guess it's what you're used to...) Anyhoo, I have a question about how this one works, since I was looking into doing something like this the other day.
Basically, is the child looking at the rotational values of the parent x frames in the past? If so that's kind of the way I was heading as I started writing, but really couldn't figure out how to do it without resorting to an expression. Whereas you are not actually running an expression here (unless I am mistaken).
Anyhoo I came up with something quite cool in the end, and more suited to the task... but this thing continued to bug me. So how does your script do what it does? Just a brief explanation in laymans terms would be great, since the language is different.
Thanks bud -
08 Oct 2006i pretty much get everything till you get into the controllers :S .
after that everything goes hazey . -
