I am at the point where we are animating the door opening and closing.
In the animation timeline for the door, I go to change the animation curve from linear to break, the handles show and I can operate them but the curve does not visually update on the main timeline, it stays very much linear.
I just noticed that if I turn the first key frame from linear into break mode it updates and seems to be correct. In the tutorial only the last key frame is changed and it seems to update both keyframes into break mode.
