[chimerax-users] Bright light while using fly command

Hi, I am trying to make a fly movie in which I move from one rotation state of the molecule to the next. Unfortunately, the lighting during the flight is not nice. The light goes very bright while moving and in the end jumps back to normal. However, if I do the turn life with mouse the light is fine. I am using soft lighting. Find attached an example movie. What could I do? Can anyone help? Best, David
