I'm using a trial version of after effects cs5.5 and have installed cc particles world into it. Whenever I'm on the program these blue wireframes take up the composition.
When I export the project as a movie file they still appear.
How can I disable them so that they won't show up again?
Those are watermarks from trial versions of the plug-in. CC plug-ins come with the paid version of AE but they are not exactly the same as the trial versions you installed. You have to purchase the software to remove the watermarks.
If I work on the same project but on a paid version of after effects will the watermarks go away? My university has after effects and has the plugins installed.
Yes, as long as the University copy has registered plug-ins.
