Ik is a character's ability to balance their weight on one foot and maintain their balance. Rigging is the process of animating an object so that it can move.
In blender, you can use the ik rig to animate a character or object by setting up the character's feet and hands with ik handles.
The benefits of it rigging include the following:
it rigging is a time-saver
it can be used to create animations in 3D software
it is easy to use, even for beginners
Ik rigging is the process of creating a system of constraints to control the movements of a character. It's an animation technique that can be used on any 3D model, but it's most commonly associated with human characters.
Rigging is an animation technique that involves setting up a series of bones, called a skeleton, and attaching various parts of the character to these bones. With rigging in Blender, there are some constraints you should be aware of.
Rigging cannot be done in any way that the animator wishes. It is constrained by the rig's limitations and the character's morphology.
Rigging can only work with a single mesh object. You cannot use multiple meshes at once for rigging.
The rig must be set up in accordance with the character's morphology and proportions - it cannot be changed after it has been created
