Squid it's literally rim light with texture + normal map support. There was a shader called Laptops Convection glow that a lot of people used but it got broken in the 2017 update so I remade it.
@ItsYaBoyy Never once got crashed for using someone else's assets. I prefer to make everything myself. I just know that people have been and instead of crying or anything I provided an (in my opinion) semi-decent alternative so that people don't have to use stole shaders.
