My bad
I just realized that the model you were talking about was entirely different from the one I edited.
My bad.
To make a horizontal revive effect, you first need to extract the model. Then you have to rotate the model along the X axis by 90 degrees. To make the model appear entirely correct, you must edit the particles so that they are rotated 90 degrees around the X axis.
Since I can't do that, I simply deleted the particles instead. Sorry for the previous post, and I hope this is what you've been trying to do.
