I'm making an animation in blender using some vrms I imported from vroid. I'm trying to delete a keyframe, that keyframe appears in the animations timeline and the top of the dope sheet. But if you scroll down the dope sheet this keyframe corresponds to no keyframe on any object, also there is no keyframe in the action editor either.
There is nothing anywhere else in this animation, just the hand and arm moving right there which I have pointed to with the red lines.
- How can I delete that last frame?
- What are the highlighted frames at the beginning and end?
The keyframes I cannot delete are always yellow. They always appear to be selected and I can't seem to deselect them. They also cannot be moved or copied.
