Hello.
Create smoke or flamme  is not easy and to much hard for
a thing so simple. But it's easy to create a disc with
a texture like smoke or flamme
The trouble is: the disc must be in front of the camera.
How can i do that?
A macros ? A .inc ? A code who do that.
Who say to the disc. Hello disc, you must rotate! The
camera translating.
Friendly.
Sylvain.

Appearances are deceptive...the reason they are hard is that they are 
*not* simple.

To specify a disc, you give a center and a normal direction. Just set 
the normal to camera location - disc center to point it at the camera.

There are fairly obvious problems with this method: reflections, 
refractions, shadows, etc. will simply look wrong, and you could end up 
with an obvious disc shape visible. This trick is usually only used in 
games and other places where you need real-time rendering, or in places 
where there isn't enough detail to notice the flaws.
