I know some of you might use it, and still want too. Don't worry, you can still use it. It's just not part of the vanilla game anymore.

All you have to do is download this http://sta.sh/01bb10se6ajo and put it in the character folder you want to play with, and rename it to "PopEffect.gif"

This is only available for version 1.3 of RIG2.

You can download RIG2 version 1.3 at my website: http://hijokegames.com/rig2
