Add more dynamics and action to Your renders
with three morphing props:
Papers - more and less caught by fire, with 'spread' and
'drop to floor' morph
Burnt Pieces - totally burnt pieces of paper with traces of amber,
with 'spread' morph
Sparks - little spark particles, with 'spread' morph
In addition, You can scale, move, or rotate every props to get
more variation. Add as many as You want; from minor incident to
Doomsday scene
I don't recommend animations, but You can get nice result with
motion blur in classic renders.
