I am currently making a Planetary Annihilation styled game in unity, and I am unsure of how to get the effects files into unity. I am trying to play the tank explosion effect when one of the tank dies, I just don't know how fbx files work nor how I could implement them into Unity 5. Any help would be greatly appreciated.
The effect files on their own are worthless without the engine to render them. So, it's not really possible to import them.
You could convert them, but I am pretty sure that the unity effects are not as powerful as PA's, so it might not work at all.
