I need help recreating an electricity effect from Jak II for PS2

Godot Version

v4.3.stable.steam [77dcf97d8]

Question

I’ve been researching non-stop to try and replicate this effect from Jak II for the PS2, in which electricity is spread randomly on meshes as far as I can see. Either when the character gets electrocuted and electric zaps touch the floor, walls, and around the character, or when the character collects “dark eco” and the same effect happens, except the color value is changed to purple.

I was wondering if any wonderful people could aid me in replicating this in Godot, an example clip is attached here: https://www.youtube.com/watch?v=VbA_42MTm8s
