Realtime fisheye or lense optic

hi,

is there a filter or plugin to simulate a fisheye or wideangle optic while running?
Or give something “more room”

thanks

attach a perspective node to your renderer, and play with the FOV (field of view) pin, or attach a camera node and zoom out (hold z and left mouse button)
is that what you mean?

there is a fish eye function inside this shader. Check it out

it is possible to build different kinds of fisheye cameras based upon the technique used here: node08.workshop.VirtualArchitecture
