Constrain on IK hand problem

Post by niravital » Fri Jul 04, 2014 10:42 pm

Hello!
First of all, I bet it's nothing new, but I really dig the Malcolm rig, it's so appealing and flexible, it's great :)

I'm doing an animation shot and in it Malcolm hold hands, so I made one hand (FK) control the other hand (IK) via parent constrain.
The problem is that when I skip to the next keyframe or even when I scrub the timeline or make a playblast, the first frame (the frame of the keyframe itself)
the IK hand is off of its correct place. Once I go one frame ahead it jumps to the correct place where I posed it.

I tried to put the constrain on different objects on different places in the hierarchy but they all seem to create the same problem.
Currently I added it to the constrain on the grp1ArmIkLf where the Chest/Body/World constrains are.

Is there a solution for this problem?
It's pretty distracting when trying to asses the animation.

I put a video example. I hope it's clear.
Please let me know if any other information is needed. Maya version is 2014.

(Sorry, don't know why the embedding of the video is not working)

Thanks,
Nir.

Okay, so after a bit more digging I came up with how to change the chest target of the parent constrain that is already in the rig.
However, I'm still having "jumping" issues when I try to parent the chest target to the FK hand. It seems to be the only problematic area
because other controllers or groups like the head or the other hand IK works fine. Just that the FK hand does not, and it gives me a "warning: cycle" type message.
Is there any connection or node that I need to disconnect in order to make it work? Or is it an already lost battle?

thanks.

Hi! We just updated to a new version that won't have that problem.

Download it now using a different email, or give me your username so we can refresh those folders.

Hi and thank you for this great rig!

I am using Maya 2015 and the IK hand controls of the Malcolm rig doesn't seem to be working. The FK for the hands works fine and so does the IK controls for the legs.

Any help would be greatly appreciated.
Thanks

Fungusbread, did you set the "ik" attribute on ctlArmIkLf to 1?
