How do I add a sprite sheet animation on top of another?

[reef junco]

I have a character already animated through sprite sheets in the animator, but now I want to add sword trail type sprite sheet to it. How should I go about this?

it will be a bit of a funky workflow but the best way to do about its is to have the sprite itself and the sword trail animation both be children under one gameobject and have its parent hold the animator instead of both the character and the slash spritesheet having their animation

you might need to do some reparenting with the animation reference but with something like notepad++ it actually is a lot faster than you think
