I am a bit confused about how to achieve this. What i want is to "draw with flames". I have achieved this with textures successfully, but now my concern is about doing this with particles to achieve the flaming effect. Am I supposed to have a Path in where i should add many particle emitters along the path that will "be emitting flames"? I understand the concept for 2d, but for 3d are the particles (that are quads) always supposed to be facing the user?

Edit:

Something else im worried about is the performance hit that will occur by having that many particle emitters, because there can be many letters and drawings at the same time. And each of these elements will have many particle emitters.
