Creating A Basic IK System
Once you have learned to create a simple IK rig, the rest of the rigging tutorials you'll read on my site and other sites will be easier to understand. This tutorial won't go through all the details of the IK system. This is just an over-view tutorial.
Step one - Download the scene robotleg.mb
Step four - Set your menu set and your shelf to animation.
Create an IK handle.
To create an IK rig, first you have to have a joint chain that's connected to an IK handle.
step one - On the animation shelf, click the IK handle to open the IK tool. Or go to skeleton>IK handle tool.
step two - First we're going to have to define our root joint, or
topmost joint (and by define I mean click on the hip joint).
Using The IK Handle
Let's test out our rig. Select the nurb circle and move it up and down. The leg will naturally bend. This is because of the IK handle. Now select the locator and move it side to side. Notice how it controls where the knee is. As you can see this is very useful for posing or animating a character. This is a basic tutorial on creating an IK rig.
