When I create a text layer, and then I click It creates a shape layer instead of a mask layer. In Aharon's tutorials it always creates a mask layer, I specifically want a mask layer so I can use the scribble effect.
I dont mean to insult in any way but make sure you have "selected" your text layer. If you dont then After effect will automatically assume that you want to create a new shape layer and fill it with the default colour in my case red. Look at that tutorial again carefully and you will see that the text layer is highlighted. I recommend that if you are following along with tutorials dont just confine your eyes to the mouse pointer but try to absorb the entire UI as a whole ie layers,settings,Tools etc. I for example always overlook the simple things in my comp and then am left kicking myself hours later when i out figure out what my mistakes were!
"The Create Outlines menu command in versions of After Effects previous to After Effects CS3 created masks on a solid layer instead of creating shapes. To achieve the same result in After Effects CS3, you can run a script to convert the shapes created by the Create Outlines command to masks on a solid layer. The script is available on Jeff Almasol’s website: http://www.adobe.com/go/learn_ae_jeffshapestomasks."
