### Eye Gaze Parameters

:::info Eye gaze normalization

Eye tracking values are normalized from the original real value range of 0 to 45, to the OSC range of 0 to 1.
These values can still exceed 1 however. Use a 2d simple directional blendtree with animations that set the rotations to 45 degree directions in order to match 1:1 with the real eye rotation
