View Full Version : IK Handle problem... (newbee question)

06-03-2007, 10:28 PM

First off all sorry about my Inglish but...
I need help with a IK Handle strange behavior in my Maya 8.5.
I have a leg with 3 joints. The hip, knee and ankle joints. When I create a IK Handle from Hip and ankle joint, after selecting the handle, and with the move tool, I can't make knee to bend. I canīt make any movements with IK Handle. I've alredy made a reset in IK Handle Tool but the problem remains....

I hope that I was clear in my explination...

Thanks for all

Do you have Modify > Evaluate Nodes > IK Solver checked?

It`s also good to have "knee" bent before applying IK.

thanks for the replay...
actually I have that option disable. But when I turned on I can only move de handle in X. When I try to move in Z and Y theres no movement...
It's very wierd...

thanks again for you time! =)

Well, if you want IK to work you have to enable that option!

And I`m not sure about that X movement. Do you mean you can only move in X axis and no other?

Or do you mean that bones you`ve created are not bending?

Can you send me that maya file, so I can have deeper look? ;)

Yes... I will send you the file... Send by email?
Thanks once again for your time...

And hey, you can stop thanking ;) That`s what forums are for.

mail send! =)

Mail sent, problem solved! ;)

I don`t know why, but there was Degrees of Freedom X unchecked:)

So, again...

Select Joint and open Attribute Editor.
In Joint rollout check X at Degrees of Freedom.

And that`s it:)

Seems like you have to do that for every joint.

Phew... we could have spent whole night guessing ;D

Quick and efficient.... A simple check unchecked! =)
Now I can continue my learning process and find another problems =)) hehehe

Thanks man! =)
