## WebAR SDK v2.0.5 Updates

We are excited to announce the release of WebAR SDK v2.0.5. This update brings significant enhancements to improve the user experience. Below are the key features and improvements included in this version.

### Instant Tracking

No hand movements or surface scanning required.

* AR appears as soon as the scene opens or the camera starts.
* Simply tap, and AR will appear instantly.

### Tap Anywhere

Place AR objects anywhere with a simple tap.

### Improved Ground Plane Alignment

* Improved ground plane alignment for better AR object placement.
* Enhanced surface detection for a more accurate experience.

### Speed Optimzations

Performance improvements for higher FPS and smoother experiences.

### Smooth Fade-In

The camera now opens with a slow fade-in effect, offering a seamless transition into the AR experience.

### Face Tracking Enhancements (A-Frame)

* New Attributes
  1. `webar-face-landmark="point: 151;"`: Attach a 3D model to a face landmark point.
  2. `webar-facemesh-shadow`: Create an additional face-mesh layer to display only shadows.
* Inbuilt Material Attributes
  1. `webar-facemat-occluder`
  2. `webar-facemat-normal`
  3. `webar-facemesh-shadow`
* Issues Fixed
  1. Replaced orthographic camera with a perspective camera for face tracking.
  2. Fixed shadow rendering issues.

**Note:**

* `webar-facemesh` and `webar-facemesh-shadow` are two different layers acting as a face mask. The `webar-facemesh-shadow` is positioned above the webar-facemesh layer.
* webar-video-plane should be placed at a negative z-distance as shown below:

  `<a-plane id="webar-video-plane" color="white" visible="true" position="0 0 -200"></a-plane>`
