I downloaded the Trial PopcornFX Supertools Trial version to experiment before I buy. I already own the PopcornFX 40, but I need to create steam for one individual character and want to see if the supertools gives me the effect I need. I am trying to visualize "smell" on an individual not the whole terrain. I have tried the PopcornFX 40 "Car Dust" and "smoke" but I want it to be more transparent. After watching the Supertools tutorial for the Steam 
texture I cannot find the diffuse photo used in the tutorial, I only have the numbers. Also, are the learning samples included with the trial version? I can't find them. Thank you.

Thank you so very much for your detailed reply. You made it very clear on what I need to do, but the export button is not activated in my iClone. I am guessing it is because I do not have the Pipeline version. See below.
If I use the Legacy "steam" how do I adjust the width?

for the legacy particles
emit volume controls the area size
as you make it bigger you will also have to increase
quota and emit rate

Thank you!
