Zones, cameras, and particle emitters all support "presets". If you would like to copy an object (say, a particle) and use it elsewhere, simply save the object as a preset and then load it in the other location. This is a great way to copy these complex object from one world to another, or even just over long distances.
When you create a preset, you must give it a name. Presets are saved as simple text files, with a special extension to denote the type of preset. The presets are saved in your Activeworlds /Presets directory, so if you come up with a great effect you can even send it to your friends so they can reproduce it as well.
Here are the extensions used:
.awz - A zone
.awp - A particle emitter
.awc - A camera object
So, if you have a favotire particle effect and you saved it with the name "sparkle", then the preset would be found at:
C:\\\Activeworlds\\\Presets\\\sparkle.awp
Note that your installation directory may differ from the example above.
If you send this file to another user, they will have that particle available in the list of presets, and will be able to create that particle anytime they like, without needing to memorize or even understand all of the numbers and settings.
Note that while the name of the particle textures are stored in the preset, the particle emitter will not work in another world unless those same textures are also avilable. Thus, you may need to change the texture names when copying particle effects from one world to another.
