[Valve Index HMD and Controllers]
While testing the 3.0 avatars, I found what I believe to be a bug with the avatar system. This was found using the Young Boy demo avatar (See picture).
When I went into the expressions, there was a menu with an analog radial wheel for controlling the eyes being open and closed. What I found was that if you have them closed (or any value), you could close the whole action menu and it would persist. However, if you have a value set, and you back out one menu, the animation is reset (the eyes snap back open to default). The value is still shown in the menu, and if you go back it snaps to that value.
I would think that users would want to be able to "lock" this value and animation so that you could keep your eyes closed, for example. In the Nanachi avatar, there were similar values for the body weight, and those persist. This leads me to wonder if the issue is related to the avatar itself or the system.
