Drag the Heart Eyes prefab located in ‘RuneFox/HeartEyes/_PREFABS’ onto your avatar. Expand it and find RightHeartParent and LeftHeartParent objects. Move, Rotate, and Scale these objects until the hearts properly cover your avatar’s eyes.
For Manual installation you’ll need to drag the prefab onto your avatar’s head bone and merge the HeartEyesFX animator into your avatar’s FX animator as well as the parameters. You’ll also likely need to remove the VRCFury components, all of which are located on the root of the prefab. Lastly, you’ll need to set the weights in the scale constraints on the hearts to 0 so your avatar does not have the eyes active when your animations are disabled.
For Quest Compatibility, find the RightHeart and LeftHeart gameobjects and replace the material in the MeshRenderer there with the Quest material located in the ’RuneFox/HeartEyes/Materials’ folder. You alternatively just drag that material onto the hearts.
Enable the hearts by navigating to the Heart Eyes menu in your expressions menu and toggle the Enabled toggle.
Activate the eyes by either doing the Thumbs Up gesture with Both hands, or by toggling the Activate Toggle.
