After using Unreal for a while I realize there are strengths and weaknesses with this structure. Essentially your ‘scene’ is your Level AND your sequence. So if you want to save as, make sure to keep the sequence and the level together (i usually keep them on the same folder) and see them as two parts of the same scene. Remember the level and the sequence are independent of each other… if you change the level those changes are not necessarily reflected in the sequences. If you save the level as something else the sequence will not automatically point to it. The good thing about this is you can make one sequence with lots of camera moves and then two versions of the level, and your sequence can be used on both…after a bit of ‘fix actor references’ if that makes sense! On another note these days I always avoid duplicating cameras and just create new ones. I’m not sure if that’s necessary but it works
