I'm a newb (over and over again, it seems) with regards to IK. I'm having the usual newbie "snapping" or "flipping" problems with my IK chains. I've searched the forums and found a couple of threads here (http://forums.newtek.com/showthread.php?137369-Why-is-leg-flip-flopping&highlight=ikplane)and here (http://forums.newtek.com/showthread.php?131749-Solid-IK-Leg-Setup&highlight=ikplane), but they refer to adding something called an "IK Plane" or "ikplane".

This seems like the only solution, but the tutorial (http://www.3dworldmag.com/2012/12/20/tutorial-get-to-grips-with-lightwave-ik/) that user "RebelHill" refers to is now behind a paywall.

I'm slowly working my way through the tutorials on line, but haven't found any that actually address this problem. Anybody got any pointers/explanations/helpful hints?

RH's link above includes a list of free tutorials that he's made available. RH Rigging Foundations 11 covers common problems...
RebelHill you are such an awesome Lightwaver and a generous person!

RH, your link is certainly a goldmine of information - do you mind if I ask a very simple question: How do you generate all the lovely blue handles and pyramids and yellow joint spheres and all those things for your rigs? They appear in most of your tutorials but I haven't yet gotten to the part where you explain where those come from. Do all those colorful doodads come from Genoma or are they add-ons or what?

Scratch my previous question. I just downloaded and opened the "RHL_Soldier" rig from your site and I think it's the most complicated LW rig I've ever seen - Your skills are far beyond my meager needs. My big takeaway from this learning experience is that Inverse Kinematics is not the "magic bullet" I previously thought, but has limitations just like keyframing bones in FK. Oh well - learning is a lifelong process and you've taught me a lot! Many thanks!

Whatever skill level there is no stupid question, especially here :)

What you ask isn't directly the Inverse Kinematics (IK). It's "Null" objects ("CTRL" + "n"). Once the creation panel is open you must click on "Edit". From there you can choose a shape, color, etc... "Null" objects are very useful in "LightWave" (target, controller, etc...).

Yes, I remember reading about them when they first came out (was it in version 9?) and thinking "oh, there's a cool feature I'll never need." Well, times change. Thanks for clarifying!
