Camera Effects binoculars

hello guys my name is john and i want to make just basic binoculars… when i press a key the camera is changing the field of view and appear a image (binocoulars shape) in camera

i khow from scripting and of course i now how to change the camera’s with .enabled but i dont khow how to do the trick-effect with the texture please help!

easiest and not expensive way to achieve that is to use a texture mask with ‘trick-effect’ image and alpha setted to 0 (transparent) where world should be visible. then, attach this texture to material with transparent-cutout shader and place material to plane. plane should be placed in front of camera.
