I've done searches on this topic and while many others have posted similar inquiries, none of them are in Lightwave and I can't seem to draw any kind of conclusion from what is posted. I'm familiar with setting up IK for human models but now I'm stuck.
I have this very simplistic model here I'd like to animate. Each segment is a bone, and each part is 100% weighted.

I went ahead and posed this thing using FK to get a better idea of how I want this thing to stand... i'm not too concerned with the joints being a little off right now as I can fix that later:

Ideally, I'd use 1 controller for each leg and use FK for fine adjustments, but the problem I have is that IK only seems to work properly on a 2-bone setup. How do I get it to work with 3 bones? Is there something I'm missing?

To give you an example of how I typically setup my models, I'll provide a human rig i've had set up. I have extra joints in place to prevent "IK pop". Basically I only set up the bones to work with pitch and I can control the legs pretty nicely, the extra bones at the top of the legs allow me to twist the legs with FK as needed.

So... does anyone have any suggestions on how I can approach the 3-joint spider leg setup using only ONE goal? Anything that could get me pointed in the right direction would be greatly appreciated!
