Maybe you could use some kind of transparent sprite overlay (this may not be the technical term). A sprite is multiple images (stored as one image) that appear one after another giving the impression of movement. Maybe you can find a particle sprite that you can put over the part. Just an idea.
You can also try a WorldModel, but I don’t know if that works.
Also, yes, I assume performance issues could happen, but it may be possible and not cause any issues if you do a good job scripting it (I think).
