Please look at the two pictures i have uploaded.
in these 2 pictures there are 2 different zoom levels 1 is zoomed in and 2 is zoomed out.
now here is the thing, outside and inside of the scope have the same FOV and thats pretty obvious if you take a close look at it. lets say it does use a render target for inside but it begs the question why would you adjust the FOV of player camera to match the render target? it doesnt make sense. whats more important for me, since the FOV of player camera is getting changed then why is it not zooming on scope mesh itself? one might think its umg but i dont think so because the lighting of the world is affecting scope material.
EDIT:I’m starting to think it’s actually a umg but with render target for scope mesh itself with some tricks, but im not really sure…
