I am looking to take a candle and change the effect from the normal candle flame, to another type of flame already provided in the Games FX effects. I recently achieved this with Sims 4, and would like to do the same thing for Sims 3.

I'm ultimately wanting to keep the on/off switch a candle provides in game, and have a different flame fx. Please help. I've searched all over google. I found a possible option, but its for Sims 2 and vague and also no where does it tell me how to get a program they're using, if it would even work.
