In fact Built in Effect and Third-party effect are creating by a very hard and time taking  development process with After Effect SDK in Visual Studio and its so hard to create plugin individuality for After Effect by using SDK.

On other hand we have Expression controllers effect that allows us to create our Custom Controllers for layers like presets but the problem with these process is that they are not looking like a Normal effect and they are well organized and we can built custom UI for them so what is the solution ?

Another types of Effects in After Effect called Presets Effect or Pseudo Effects that have Different controllers , Groups and Custom Text that looks like a Effect Plugin and control different properties of layers , In this class i am going to teach how to create these types of Custom effects using Flex Effector Script in After Effect .
