Hi Team ,
when i am trying to use default camera pixel resolution settings and focal length alone updated (approx 90degrees H) along with radial distortion coefficients . i am getting the stripes at edge of image ,same excercise when i carried out with less pixel resolution i am not getting the stripes, please do let me know why the change in FOV especially in case of broader FOV this is happening.

This is the other image with 130deg FOV & applied distortion

The Simulation 3D Camera is best used for cameras with a narrow field of view (<= 60 degrees), and use of the Simulation 3D Fisheye Camera is recommend for larger angles. MathWorks has a calibration procedure for fisheye images. It may be most useful to calibrate the actual camera hardware this way; the mapping coefficients in a fisheyeIntrinsics object should be the same coefficients used to distort the image in the Simulation 3D Fisheye Camera.
This is a known limitation with how Unreal Engine samples the 3D environment into an image in a performant way. This may be improved on in a future product release.
