# What's New? ### **WebAR SDK** \ Added new API **`SetFaceScaleFactor()`** for face tracking\ It configures the scale at which AR objects are displayed relative to the user’s face in a web-based AR experience. ### **Unity** \ As part of Release 1.7.4 an enhancement has been deployed to Unity build release v.1.7.4-1 with **peel-away mod**e. Enable this feature to allow the object to be displayed even when the user moves the camera away from the marker, the AR object will still remain on the screen.
