Hello, I’d like to ‘transform’ my face with ARKit, SceneKit and TrueDepth camera.
One example is here : https://twitter.com/yt/status/1078534130416013312
To implement this, two images (Y and CbCr) are sent to a Metal shader, and they are converted to RGB in the shader as next document says.

But the face drawn by my shader becomes a little bit whiter than other (See the example video).
I set some SCNLightingModel to face’s SCNMaterial object, but this did not work.
The conversion from YCbCr to RGB is not enough? Do I need to do something more?
Thanks in advance.
