I don’t know why the page numbering in this thread is so weird, but my last thread about render scripts does the same thing. I guess I’m just special.
In any case, yes, I know how to use ctrl-click, I’m just trying to find a way to set up a script that the user won’t have to do this with, as many new users don’t know about it. And I think ditching all the cameras in a scene when loading a new camera is a bit weird, to be honest. I can sort of understand this with light sets, but cameras don’t interfere with one another. Set the loaded camera as the active camera, sure, but sometimes there are good reasons to have more than one camera in a scene, especially if some of them have special effects.
