Perspective issue - 16:9 vs 32:9

I'm attempting to render larger width rooms that span approximately a 32:9 width, but maintain the perspective of the left/right walls as if they were still in 16:9. For example, in the 16:9 image it has a 45 degree angle at its walls, but in the 31:9 image it has a 60 degree angle. I understand a lot of this is just FOV, frame depth, etc., but I really need to find a way to force the walls to adhere to a 45 degree angle while maintaining Perspective on inside the camera settings. Stitching them together from multiple renders isn't an option as I'll be using canvases for props once the room is decorated, and stitching them together leaves too much room for error. I need to find a solution in a single camera/single render, but for the life of me can't get the camera settings to play right.

Any suggestions are greatly appreciated.

    I don't think you can change basic geometry.

    I suppose you could try to create a fisheye effect using lens distortions in the camera. But that will warp the contents of the room, too.

    On the 32:9 have you tried setting focal length to 120?

    You will get a zoom effect but kind of kepping perspectiv.

    With wider screen rendering,  the stretching / distortion near the left / right sides is mainly caused by perspective projection combined with the extremely wide horizontal field of FOV.

    As you set 32:9, the render extended much farther to the sides of the camera's optical axis, then the walls near the edges appeared increasingly stretched as their viewing angle became much larger.

    In such a case, the common way to improve it is to : either reduce 1/2 of Frame Width or double Focal Length, then zoom out with the current camera...  sort of like when photographing with a real camera, compress the background with a telephoto lens.

    Thanks, everyone. I figured it was just a matter of the geometry and aspect ratio, and thus nothing I can truly fix but wanted to ask.
