User:Toady Nakamura/Particle Mist for Fountains Script

Particle System 1.0

• This script will make steady mist, useful for fountains, fire logs, small waterfalls and so on.
• Once the script has done its job and made the particles, you can take the script out of the prim to save on script load.
• Be sure you keep a scripted copy in inventory in case you wish to use it later.
