## Parameters

### Right hand

When enabled the weapon will be used in the Righ Hand, when is disabled the weapon will be used in the left hand

### Aim IK Left&#x20;

Aim IK profile to be used when the weapon is left-handed.

### Aim IK Right&#x20;

Aim IK profile to be used when the weapon is right-handed.

{% hint style="info" %}
The IK Profiles are enabled using the IK Aim Animation curve
{% endhint %}

### IK Aim Animation Curve

Shooteable weapons require an Animation Curve called '**IKAim'** on their animation clips. This will set the weight of the IK Aim profile to correct the pose of the Human body to aim properly

That IKAim is then read from the Animator Controller to set the IK Weight for Aiming the weapon

### IK Hand Right&#x20;

Reference for the IK Goal for the auxiliary hand if the Hand is 2-handed and the Main Hand of the weapon is the left-hand

Make sure all your weapon animations have the curve IKFreeHand properly set as an animation curve

This will set the proper weight to activate the IK for the Auxiliary Hand.

Some animations will require a more refined curve like an attack when the auxiliary hand needs to be released for a moment:
