Wondering if anybody knows how this is done in games.
When using FOV to zoom the screen in order to replicate a scope zoom, you encounter a problem where you can see the inside of the scope housing. In games like battlefield/cod, it almost looks like picture in picture, where you have a lens almost acting as a screen, but as far as I know, they are definitely dont use PIP.
Its almost like the back of the scope gets kept and the rest gets hidden? Do you know how games do this?
