Flames

I have the Indie version of Unity and none of the standard flames and smoke look like this. Is this only possible with the Pro version? If not what am I doing wrong? I can get the flames to work by themselves but not the smoke. The flames are additive so the smoke does not work since it is dark and would need a subrtactive shader which I do not have. If I use a second material for smoke using alpha it covers up the flames and does not fade out at the end like the flames do.

Thanks, Andy

 

That screenshot was made using the Particle AddMul shader. It works like this: Color gets added alpha gets multiplied on to whatever is there. It is your friend for doing flames+smoke kind of effects.
