Spherical 360 getting distortion

Hi everyone, I’m getting lens distortion and not getting rendered in the poles while using the spherical 360 override. FOV shouldn’t be affecting since I’m overriding it.

Not sure what you mean by “getting rendered in the poles”.
Your cam rotation P & B values must be 0 degree.
