How can I adjust keyframes of multiple objects when some are invisible? I have set up a scene with many objects at 24fps. Now, I increased it to 60 fps (2.5 times more). To keep everything at the same speed, I increased my frame count by 2.5 times. However, I cannot do the same for my objects as some are invisible in both rendering and the viewport. (Easier for previews) I do not want to have to remove their keyframes one by one and re-add them. How should I get about doing this? Is there something in the graph editor I can use?
Yes, you can do that. At the bottom of the graph editor there is a ghost button:



Push it in, and now you need to make everything visible in the viewport. Since it is keyframed, this won't do anything. Then, without changing frame enter a. You can now return to the graph editor and edit everything. I just needed to reset the 3d cursor and resize everything
