I'm trying to create a "laser wall" in Unity that's similar to the reference image below. I'm thinking about modeling a plane that has the desired shape, creating an emissive texture for the laser effect, putting a material with Particles / Additive Shader, then using a script to animate the intensity and noise to make it look a little bit dynamic.

I was wondering if it's possible to create a custom shader that automates the process of making a more complex shaped plane look like a laser barrier. The shader would detect the edges of the plane, then apply a brightly colored border on those edges while the middle portion of the plane will look like a tinted translucent wall. This way, it would be very easy to just model the shape then slap a material without creating a different emissive texture for each different shape.
please help.
Thanks.

I didn't find the right solution from the internet.
