that can be done too, if you played as-supermarket you know what I mean
GTA has its limits too but if you are clever you can create your own special effects, you have seen the snow tutorial, the ion cannon, somebody made a meteor rain, you can use coronas/checkpoints/cylinders to create all kinds of effects
I don't really know why the author removed it sloppy coding probably! but you can create your own if you want, just hide the tags and use GUI
