Vision cone using post process material

If anyone ends up here.
I finally ends up with a solution, but that wasn’t an easy one, took me a looooooooooot of research, and TOO MUCH MATH. If you don’t remember how to calculate cosine or even what it is, it’s fine me neither 2 days ago :')

All calculated and drawn by the GPU without masking or anything.
Kinda proud on that one ahah

Maybe I’ll do a more detail post of what I did but for now I need to touch some grass
