Applying different shaders to meshes

Question

I have meshes, which applied video texture. I want to apply different shaders on those meshes (for example, monochrome and sepia). Now I can see only one of them. In this example only second (2). If I comment (2), I will see (1). How I can see both?

  onRenderFcts.push(function(delta, now) {
    composer.render(delta); //(1)
    composerGray.render(delta); //(2)
  })

Answer 1

I found a solution. Now I have been using standard postprocessing and shaders things. Without extention THREEx.js and strange for me blocks of code.
