Hot Air Effect

Hi,

I’m trying to learn how to make “hot air” effect around the engine, for examle plane engine.
Could someone point me out, how to make such effect, or maybe some tutorial or something.

For clarification what I mean by “hot air”, please look at this movie:

Any help would be appreciated.

You need to make a material similar to “frosted” glass. Basically it’s a refraction shader with some noisy normal map, kind of what is used for water refraction or underwater effect. Then you drop this materials on simple particle system with a circle spawner mesh (specifically for this type of heat “source”).

Thank you, I will try it out today. If I get some satysfing result, I will describe it here.
