View Full Version : Smooth IK - Soft Solver issue

Hi guys,

here I have a little and complex (at least for me) question: how can I avoid the tedious snap effect happening when I make, for example, an arm stay straight from a bent position.

Example: frame 1 the arm is bent at the elbow level, frame 5 the arm is straight and the snapping effect comes.

Another question: is writing an integral into an expression possible with maya?

Thank you very much in advance

The elastik solver (http://michael-hutchinson.com/downloads/index.php) may be what you're looking for. I haven't tried it myself, but it has some pretty cool features.

The other alternative is to key the arm stretch frame-by-frame to avoid IK snap. This only works if your rig has arm stretch, obviously, and it's a bit tedious, but it works well (especially if you use something like cMotionTrail to track the spacing/arc on the elbow or knee joint).

Yes I know it, but unfortunately the plugin is not for Maya 2008 that is the Maya version I'm using (Maya 2008 x64 ext 2).

Thank you anyway

if your setup has stretchy limbs attribute play with them to remove the ikSnap

its known problem, i personally solves it by increasing shoulder and wrist stretch(not autostretch).

check http://3drigger.com/sunny

for quick example of what i am saying..

me and my collegue wrote a script to automate a process for doing softIk I could share it I guess.
It's based on the XSI tut find here (http://forums.cgsociety.org/www.xsi-blog.com/archives/108).
Will ask if we can share it on monday.

cheers
