Hi mate

the bones need to be rested and keyed at frame zero.

Then position your goal without parenting to the object.

Setup the chain with the goal as target and select 'go to goal'

good luck

p.s. i'm a noob so checkout the pro technique

Thanks a lot for your answer i have one idea about this problem...

i worked the body of my model in 3d max and then i convert in Obj and then i use Blender to convert in Lightwave object and that is the problem, the Ik don't work fine in that, i don't know why.

i use the IK in a simple box create in the modeler and then i do the Leg rig in the layout and works fine, but when i use the ik in import objects... i have the same problem.....

Any body knows why happens this?

Make sure before applying IK to the bones that you prebend the knee to indicate to the IK solver which direction the leg is supposed to bend.
Make sure on the knee what IK is applied to one channel only.
