two things 1 : camera boom length determines how far from the player the camera is - moving it around will mess with pivots and break your rotations 2 : it might be an idea to explain all the things you want to happen when you press the button as well as all the things you don't want to happen.
I've faced with a problem and i need to change my reference mesh at the middle of retopo process, how can i do it? I can't find any button to "Change reference mesh" or import it.
