Hello.
I am currently writing a custom camera based on the Physical camera.
If you render out of a Physical camera and adjust the camera distortion, it will work. however, the camera distortion parameter (distortion_cubic_amount) will not be taken into consideration if I use my extended camera based on the same camera class. I see de difference of the view cone in the viewport though, so the value gets through. Also everything works as expected if i change the focal length...
plugin camera lumière_camera
