Double click the icon to access properties. Hit Add …

From the drop down, select SpriteEmitter

This shows a smoke texture [has an alpha channel]

Open the properties for the emitter again and hit Use to apply the texture … now you will get to see the smoke in action …

Back to the emitter … this shows some properties of the sprite emitter:


Scroll down farther … under texture, in the drop down, under DrawStyle, pick alpha blend

Set up the size range of the faces that are emitted … you only need to specify X …

Velocity  sets the speed of the particles … set the Y StartVelocityRange to see the smoke move across the screen …

Lifetime range is the life span of any one particle …

Fade in and out is the opacity fading of particles … set FadeIn and FadeOut to true … also set FadeIn to fade in at 1 second and start to FadeOut at 2 seconds:

Make the particles more transparent:
