View Full Version : IK Not Following Goal Correctly

Hello,
Please if any one can help me here.
Simple thing for the experienced I am sure.

I have a Long Hose I am animating.
It has 51 bones all inverse kinematic applied with a goal.

When I animate it, the hose jumps around a little and does not follow the path of the goal object to produce a smooth movement.

I tried increasing Goal Strength and it has no change.

Please I need to have this working today.

Thanks,
Scott

How high is the goal strength? set it insanely high, like 1000 or more.

Also, does it still miss the goal when you do a preview or test render? Sometimes IK can be jumpy in GL display, but will work right in the end.

Let me know.

Hi Rob

Thank you for your help.
I just rendered it at Goal strength 1000 and it is still as jumpy as goal strength 1.

Is this for a commercial project, and/or are you willing to spend $200?

Worley Labs (www.worley.com) has a plugin collection called "Taft" that will do hoses automatically.

Also, check the stiffness on your bones. Try turning it all the way down for all the bones.

Hopefully, we're getting closer...

You could also try using constraints for the HPB on each bone, or use serpent if you know the rout some of your hose is going on, and/or use a path motion for some of the hose's bones...just a thought...

If I'm not mistaken, you can also set multiple goals along your chain of bones... Every few bones have a goal that pulls that part of the hose to the place you need it.

I've not tired this, I'm just kinda shooting in the dark...

Thank you Rob,
You mentionned turning Stiffness way down.

I turned it to zero and it got worse.
Then I Moved the stiffness for every bone to 10!!!!!

BAM BAM it Worked!! Thank you!!
