Manual animation modifies previous built-in motion

I added a built-in dance animation to my G3 character, and it plays correctly. However, after the dance animation ends, I want to manually continue animating my character — specifically, to move the arms in order to complete the dance motion and finish it smoothly. I’m doing this a few frames after the animation ends, but when I pose the arms the way I want, it changes the entire dance animation that came before, even though I added keyframes at the end of the dance animation for all the body parts I later adjusted (both arms and all relevant segments). Why is this happening, and how can I continue animating the character without affecting the built-in animation that was applied earlier? Thank you.

Hi…

Please try this:

Open the Timeline and on the last frame of the Motion Clip, double click the Transform track to open the 2D Motion Editor. Now select “Set Key” which will place a keyframe on the Transform track.

Now when you add further keys after the motion clip it should not affect the motion clip itself.
