Editing Shaders?

[zionifl]

Hi, it's me again. If you had seen my previous posts here at the forum, it's certain that you know who i am. Again, i am here to seek help.

This time, it is an continuation of my "blue light around entities" thread. I discovered that it is an shader that makes the specific effect. Those shaders are "game_outline_frag.glsl" and "game_outline_vtx.glsl". Is there any way of editing those shaders so that it apply, not only to pickable items, but to interactable entities? Again, this is for my project and i understand if editing those shaders is not possible.
