Belatedly, I note your recent "joined" date.  If you don't model (yes? no?), you can still do this.  Load a primitive prop, either the sphere or the capsule, whichever most closely fits the shape of the flame in the torch.  Move it to surround the flame, and scale it to contain the flame, preferably without intersecting the wall.  That will be your emitter.  Now Use edit: duplicate ball_1 to make another sphere, and scale it up about 150% to 200%;  this will be the "glow" aura.

     In the parameters panel, click the properties tab, and for the emitter, untick both the casts shadows box and the visible in camera box.  For the glowing aura prop, untick the casts shadows box.

     I'll need to make some screenshots to help explain and make material files for you.  Check back later.

edit:  On further thought, please post a screenshot of a preview closeup of the flame part of the torch, showing also the end of the non-burning shaft.  It may be simpler for me to make a substitute torch end, with emitter and aura.  ^^
