This script, like maya's instancer, makes particles replacement, but
uses object's copies instead of instances.
This allows users to edit every single object and change its animation manually or delete some of them, it generally fits the animation to your desires.
This way of instancing also avoids maya's instancing bugs at render time, 'cause objects are copies and not instances.
With alien Replacer you can replace everything, ligths and emitters too.
You can assign a different material to every single object.
Objects are animated by keyframes at the required frame step and with the required key tangents.
