I have been out of the loop for the past year-and-a-half—fighting cancer. I am back on my feet now. My last version of Blender was 2.79. Upon my return, I am suddenly up to 2.90. Just about everything is now different, and it has been a struggle to get back on track.
My question today, concerns applying rotation to a camera. When a camera object is created, it is pointing straight down. I want to set my own reference direction—for example, “due east”. However, when I try to apply the transform (ctrl-A) I get an error saying “Object has not data to transform!”
I used to be able (with 2.79) to apply rotation to a camera. What has changed? Do I need to do some special procedure? Accurate camera rotation is now extremely difficult, as the axes are all jacked-around.
