How to use Aim-IK in Unity-3D?

Here are the following steps to using Aim-IK in Unity-3D:

• At first, create a new project in Unity-3D.
• Add your Rigged model.
• Download Aim-IK DLL or Aim-IK Unity Package file.
  • If you download the Aim-IK.dll file, you should make a folder in your Unity Assets folder with the name Plugin. Then put Aim-IK.dll file to it.
  • But if you downloaded Aim-IK.unitypackage file, go to Unity. In the Assets folder, press right-click and then click on Import package > Custom Package.... Then choose Aim-IK.unitypackage and click on Import button.
• Now, Aim-IK is ready to use!
• Select your model.
• Press Add Component. Follow Scripts > AimIK > Aim IK Behaviour.
• In the Aim IK Behaviour script, you see some properties.
• In the Target property, select the target object.
• By enabling the Smooth Look At check-box, the character smooth looks at the target.
• If you enable the Smooth Look At, you should set a value in Smooth Time property (The standard value of Smooth Time is between [0, 1]. By increasing it, the character looks at the target faster).
• In the Head property, you see these options:
  • In the Part property, select the head rig (NOTE: Be aware to don't add head model! You must add head rig).
  • Another property is Position Offset. You can use it to set the eye position offset to the head character.
  • The next property is Rotation Offset. You can use it to set the rotation offset to the head.
  • So if you want to limit the head rotation in the z axis between two Min and Max variables, you can use the Head Limit Rotation option (NOTE: If you want to limit the rotation, enable Active check-box).
• OK, now press Run and you see the head of the character, looks at the target. Cool!
• And the last property is Chest Parts. It's an array that you can choose other chest parts that you want to look at the target.
  • NOTE: Each chest part, has Part, Position Offset, Rotation Offset and Limit Rotation (like the head).
  • In the Part property, select part rig (Be aware to don't add part model! You must add part rig!).
  • In the Position Offset property, set position offset to the part model.
  • In the Rotation Offset property, set rotation offset to the part model.
  • In the Limit Rotation property, limit the part rotation in 3 x, y and z axes between two Min and Max variables.
