So, in the video you select one bone of the antenae and hit L to select all and then i to key all at once on the first frame. for some reason when I follow those steps it only keys the active bone. am I missing something? (blender 3.3)
Hey I am working the same project. Not sure I understand what you are doing, but if you have all the bones selected. then go to the graph editor (make sure your mouse is hovering over the graph editor) click "I" on your keyboard and you will see a pop up menu. Select "only selected channels" you should see key frames on all bones. hope that helps.
