Wow. Seems there’s no way in the editor proper to copy the camera animation filenamed GameName_level02 .anim file and put it onto the camera (or just copy it period) for my level_3 camera, which shares the entire animation, except an additional last 2 frames.
So I just did a windows search for Level02_CameraShake across my entire drive, and it came up with Level02_CameraShake.anim.meta.
Single-Clicked on the file, right clicked, chose “Open file location” and there are two files:
Level02_CameraShake.anim.meta.
and
Level02_CameraShake.anim
Copy/pasted both, renamed to:
Level03_CameraShake.anim.meta.
and
Level03_CameraShake.anim
Back in editor, I opened AnimaTOR (which now shows Level03 animation box) and clicked on the Level03_CameraShake.anim. In the Inspector I clicked the motion file, and pointed it toward the Level03 camera shake animation file. In the animaTOR, I deleted the auto-created ‘error’ anims (there were several), then saved as GameName_Level03_backup and then exited. On restarting, the caution prompts were gone and it seems to have worked. To be able to copy/paste animation from one object to another would be a great feature.
