I created and released this nearly 10 years ago! and still to this day i get regular requests for the file, Google drive has not allowed anyone access to this file in so long, I have no idea why, i guess it just Expired, anyway heres a new link for it if anyone wants it, and ill say again, this is nearly 10 years old, i have no idea if this works in the current version of unreal engine or not.
Also note this worked at the time by drawing many many decals, which i know now is poor performance, and suggest looking up a guide doing this using shaders.
