Animated television static effect, techniques? iPhone shader
I'm trying to create a television static effect. My best guess is create it using a few images and altering the UV rapidly, put it on a cube or plane in front of the camera, then alter the transparency to fade it in and out.
I would like to ask is this done using a shader? I need to layer 2 or 3 semi-transparent images on top of each other...moving each one in different directions to create the static effect and another layer to create a slow vertical shift.
I'm targeting iPhone so is this a limiting factor creating transparent shaders with 3 layers?
Any ideas on how to achieve this effect would help. THanks.

When exporting your file to FBX the plugin gives the following error. Can these FBX export warnings have something to do with it?
The plug-in has detected mesh nodes with unsupported operators that affect the vertex and/or face count. To correct this, delete the Non-deformer history before exporting. The following nodes will not be processed: AV_sixpoint6:Group17709
Irrelevant; this probably has to do with some other question, and questions are not answers. Please delete.
I took his file and tried exporting it to fbx and the exporter gives the quoted warning. How is that irrelevant?

I believe this is what you want. Forget the transparency:
