Usage & Common Problems

This is a relatively rare bug where the color theme of Randomill failed to load for some reason. This bug should be fixed as of v1.1.4.

Processing large groups of objects can take a while due to the way that Illustrator allows external plug-ins and extensions to interface with it. For instance, random selection can take a while because objects are selected one at a time by having their ‘selected’ attribute changed inside of Illustrator. When you’re operating on thousands of objects at once, it can take a while. That being said, Randomill is optimized for performance as much as it can be. After testing performance of other comparable scripts/extensions, Randomill performs as good or better.

Randomill treats groups as single objects. This was intended to work as a way to cluster objects together during Randomization. For example, when randomizing colors in a grid of squares, you can group a few squares together, and their colors will all end up being the same.
