  • How to create a custom effect

    Posted by Ben Mcallister on March 2, 2010 at 12:27 pm

    I have created a very nice camera rig that uses five different null objects and connected them together with expressions. X, Y, Z rotation, zoom and a master controller null with all the angle controls and sliders linked together.

    This is a pain to setup each and every time I want to use it as I have to add the nulls, make them 3D, link their various parameters to their respective controllers on the master null (You see what I mean…)

    I’m looking for some way to make my own custom effect which automatically adds the nulls, camera and related expressions all once.

    Animation presets do not help as I need all the elements added to my timeline at the same time.

    Are we talking simple preset of full-blown plugin?

    Any ideas would be great, Thanks…

    you can’t do all of it with a preset (as you’ve found), but you could create a series of presets for each null that has a slider/effect control and the camera that links the camera controls to the sliders and nulls.

    still a bunch of steps, but easier than doing it manually.

    otherwise you’ll need to write a script that will create the nulls, name them, add the sliders (name them if needed), add the camera and add expressions to link the camera controls as needed… not an easy script, but if you know some java, you may be able to make it.

    here’s a page with an introduction to scripting in ae:

    and of course, there’s the ae expressions forum (lead, in part, by the guy who wrote that page, dan ebberts).

    Thanks but I was kind of hoping to avoid that…

    I just saved my rig as a .aep file then import it into any new comp, making sure to change the original precomp size to match my targets comp size then copy all the nulls with my camera and copy the solids into my new comp. Ready to go…

    But still writing a script sounds like something I’d like to have a go at. Thanks for the link.

    yep, i love expressions, but scripts are a bit beyond me…

    the setup comp is a good idea, you should be able to import that project into any project to effectively load the camera rig whenever you need it.

    Thanks I’ve done exactly that.
