Adding glitch effect to different object in a scene

Hi everyone,

I’m still a newbie to threejs, so pardon me if this is a dumb question.

I was able to adding glitch effect to the entire scene. But what I want to do is to have different objects in different place of the website (I set my scene as a background for the site), and adding that effect to the objects. Would it be possible to do that?

possible but not an easy thing to do if you are

Possible. One of solution is add to glitch shader to material of object. Need to use onBeforeCompile.
This code chaning normalMap texture repeating:

shader.fragmentShader=shader.fragmentShader.replace("#include <normal_fragment_maps>",
`vec3 mapN=texture2D(normalMap,vUv/40.0).xyz*2.0-1.0;
