So I just came along this post by Danny Groleau, and want to mention that not only is he completely right, but also want to add that you can use ParticleEffects for much more than that. I primarily use them as static effects for different atmospheres, as they are cheap solutions for:
|The sun rays on the right spot, little particles around the area, all solved with|
cheap particle effects.
|What a great atmosphere. The combination of the waterfall, the splashes and the light rays|
makes a wonderful picture.
|Look at the fog and the small particles surrounding the building.|
