Hi @tiagomcoliveira, thanks for your query. You could try using the following property on extended view script:
public virtual Camera CameraWithExtendedView
Which is a full transform of extended view camera and one can calculate rotation diff between it and CameraWithExtendedView rotation
or one could simply use CameraWithExtendedView forward vector as a movement direction.
However, we would not recommend using Extended view for navigation, unless it’s fully assistive use case. Let us know how you get on. Best Wishes.
