Hi I'm trying to achieve the red dots with a shader. I tried doing it with polar coordinates but it always ends up stretched. Any idea how to do it?
I'm using shader graph btw.

After converting to polar coordinates, you need to then scale the UVs by the screen resolution (or object scale if it's not a screen-space shader). _ScreenParams contains that info:
