Orthographic Camera / Auto Calculate Ortho Planes Issue

[thegattis]

Hi all, I see that there are some recent additions in 5.4 to orthographic camera settings. One of them being “Auto Calculate Ortho Planes”.

I am noticing that when I enable “Auto Calculate Ortho Planes”, any translations I make to the camera do not affect the camera at all.

Is this expected behavior?

I’m using Unreal Engine 5.4.3, and to showcase this behavior I created a new project from the Third Person template and changed a few minimal settings on the camera on the BP_ThirdPersonCharacter:

• Change camera projection mode to Orthographic
• Uncheck Use Pawn Control Rotation, Inherit Pitch, Inherit Yaw and Inherit Roll on the Camera Boom.

After changing those settings, if you hit play and try to translate the camera the camera moves as expected, but while in the play session, if you eject and check the “Auto Calculate Ortho Planes” setting, the camera will snap back to local origin, as if there was no translation applied.

I have the same problem.

this seems to solve the problem for me.
