Fisheye Lens effect in game UPBGE 3.6.1.
All I realized that I couldn’t use the panorama lens in eevee or in the game engine.
I then looks at Python to change the camera setting to get the desired lens distortion, where objects nearest the center are large and straight and they get smaller and warped as they get farther away.
Then I though maybe I can get a shader to make this effect work but I have been unable to find a tutorial on 2d filters and I don’t have a clue.
