Lets add some hands to VR Player using the Oculus free hands model and get some basic animation rolling😆

OCULUS FREE HAND MODEL

Getting The Hand Models

Using Unity Asset Store or the Package Manager window, find the Oculus Integration SDK

Download only the CustomHands folder and the TouchControllers folder. Once done, erase the Scripts folder to remove some errors you will encounter.

USING VR HAND ON UNITY

Basic Hand Animations

Find the Models folder to get a simple hand, drag the l_hand_skeletal_lowres (this is the left hand) object to the Hierarchy; add the LeftHandAnimator controller to the Animator component of the hand.

Create a new script, named it VRHands and add it to the l_hand_skeletal_lowres as a component, take a note to add the namespace using UnityEngine.XR.Interaction.Toolkit on top of your script. Change the Transform values just like the one on the image.

Give a shoutout and a BIG thanks to David Brown for the simple script to use on the VR Hands👏

Drag the hand to your designated Prefabs folder and repeat the same steps for the Right Hand, note the difference in the Z rotation for the Right Hand.

Changing VR Hands Color

Create a new material with the color of your choosing, open the Hands prefab and find the object that hold the Skimmed Mesh Renderer and place the material into the Materials Element 0

Adding Hand To Your XR Player

Go to your XR Player, find your LeftHand Controller / RightHand Controller, on your XR Controller (Action-based) script component add the hands prefab to the Model Prefab field and on the XR Direct Interactor component make sure the Hide Controller On Select is check, this will allowed your hands to disappeared when picking up object.
