Steam... Smoke... Mist...
Each of these connotes something hidden, dark or mysterious. Monsters
lurk in the fog; vampires emerge from the misty night; demons leap out
from the smoke of a magical fire. What's a cauldron bubbling over a fire
without a strange vapor emanating from the liquid within? And where
there is fire, there should also be smoke.
Immerse your characters in a dense fog, or a steamy bath.
Let your character's breath create a mist in a wintery scene. Let the
fire grow smokey. Change the prop ambient color to a yellowish or
brownish one for an effect to appear as a desert sandstorm. Or if a mad
scientist experiments in his laboratory, change the ambient colour of a
SteamZ prop to poison green or bloody red and you a have fitting
atmosphere for that scene! Let your imagination determine how these
props should be used. Add mystery to your runtime, and explore the
mists. Go ahead. It's only fog, right?
