I've asked this for a square sticker effect 2 years ago, but now I'm making a sticker for another Rubik's Cube that isn't in the shape of a square. Each sticker is shaped oddly.

I've tried this on a sticker, and you can see that the effect only works on the far outer edges but none of the other edges. Is there a trick to make the effect work for all edges?

My post 2 years ago for simple plain just if you needed to see it, but now my stickers are oddly shaped. ([https://blender.stackexchange.com/questions/254964/plane-edge-wear][1])
