Camera FOV is incorrect in Play mode UE5.3

[llixsee]

This was ok in 5.2.
to reproduce: Create new empty project in 5.3 and start play mode. You will notice, that fov is different in play mode, despite the fact it is still 90 for both modes. What’s wrong?

Same here

I also have this issue

Same problem. For my game (mobile) I optimized all LODs, cull distances etc. for a particular 50 deg FOV. After converting the project to 5.3, FOV became so small I had to increase it to 110. Now I have to tweak all LODs, cull distances, terrains… I hope there is a way to fix this…

I’m having this issue as well, it also messes with cutscenes by suddenly changing the fov because for some reason the fov issue doesn’t happen for cine cameras

Found an answer. In 5.3 they have changed default FOV setting in engine.

But, thankfully, you can change those in camera options tab of your camera:

Ah, I think I found the reason behind this: Unreal 5.3 added a new camera property in the camera options which is called “aspect ratio axis constraint”. In my case it had the wrong settings by default.

Yeah, that’s the cause! Adding this to my DefaultEngine.ini fixes it (since it’s not the bug but feature ):

[/Script/Engine.LocalPlayer]
AspectRatioAxisConstraint = AspectRatio_MaintainXFOV

thank you for finding the answer!

this new FOV setting broke ‘CamQuery → Get Field of View’ node inside Niagara as well.
Changing the camera setting to ‘Maintain X-Axis FOV’ fixes it.
