So, long story short- I'm making a maritime map, and I need to convey the rocking motions of a ship. As it stands, the env_shake entity works for my purposes, with one caveat: with a high amplitude and low frequency, very noticeable 'hitching' occurs, where the viewpoint jumps from one angle to another instantaneously. Now, I'm okay with making people slightly nauseous, but this is just plain unplayable. Does anyone know of a workaround?
