I’m trying to setup IK on a character and the arms are acting a little strange. Does UE4 have something similar to Maya pole vectors for controlling limb rotation during IK?
Thanks.
Hi!
UE4’s equivalent of a pole vector is called the IK’s ‘Joint Target’. Just like the settings for the End Effector, you can specify a point in the space of a bone in your skeleton. So, in the case of an arm IK setup, you would select Bone Space for the Joint Target, pick the lower arm/elbow joint, and then give it some offset from the elbow (like a pole vector would have). Same thing with a leg, you could specify Bone Space, pick the lower leg/knee, and then give it an offset to move it a bit in front of the knee. Again, that will put it right where a pole vector would be in a Maya rig.
Here’s a screengrab of what a leg IK setup might look like:
Good luck, and if any of that is unclear, just yell.
I think this is what I’m looking for too Ray. Many thanks. However on my Two Bone IK settings I only get half of the details in which you get with your settings. Is there a way to expand them?
Sorry, for the delayed response. I just saw this. If you uncheck the boxes labeled “As Pin”, you should see all of the options in the Details panel.
i think i’m missing something.
i’ve implemented my IK’s same as the picture you have provided shows, and my animation acts… well… funny?

any ideas on what could have cause it?
thanks.
try using the newer leg ik nodes, that tends to work well
