I'm using a sphere as a skydome to place a sky image .jpg for my background.Everything looks fine in all viewports except my camera view where the sky doesn't show. I've tried everything I could think of and nothing has worked.The sky also renders fine in all viewports except the camera view. I tried creating a new camera and I get the same results. Using a target camera.

Hi, did you put it in the image plane in camera settings?

Select the Sphere you are using as sky dome and apply shell on it

apply shell on sphere
