If you are seated, the character is short by default. You have to use the slider every time. There should be some calibration and default height, as in Skyrim and every other VR game. In addition, it would be great to have either an auto-detect for seated vs standing in the same play through so we can sit when in a vehicle (again, like Skyrim), or at least calibrate using the options button. Right now, it is not possible to sit after standing in the same game and use a vehicle. You can massive clipping and no calibration.
