[4.6 preview] camera editor falls down endlessly

Hi,

Don’t know what happened, 4.6 seemed to work fine.

I updated my code, suppressed all the warnings, made a few changes, so i don’t know what triggered the problem.

Now when i open the editor, the viewport camera starts falling down and never stops. I can still control the camera, but it’s like i was constantly pressing the down button.

I am mostly doing c++ so i just let it fall and don’t care for the moment, but the viewport is completely unusable.

Edit: It’s not related to my project. I created a test project from the c++ puzzle template and got the same behavior, right after compilation. The first time i opened the project, the viewport camera started falling down.

well, i stopped caring, continued my dev/trials/errors/compilations for a few hours.

I didn’t touch the editor except for stop/start, and now it works correctly again, with no more apparent reason than when it stopped working.

No idea what happened, i will update again if the problem comes back.

This just happened to me. Everything was fine when I closed the editor this morning, and now this.

Hey and honaj-

Could you elaborate on what you mean by the camera falls endlessly? Does this happen during PIE or are you referring to the viewport as soon as the editor opens? Are you using the 4.6 preview from the launcher or are you working with the source code from GitHub? Also , am I correct in understand that this happened to you in a new project that was created/built with nothing added?

The editor viewport camera is slowly tilting downwards. I’m using the preview downloaded from the launcher.

Hi ,

First of all, my problem stopped 3 days ago, everything is fine since then (~4 hours of ue4/day). It lasted a few hours and then went back to normal. Magic.

I am working on 4.6 from the launcher (never compiled the github code in my life).

Yes, right in the editor, without touching the play button, no pie, no standalone, no game. I opened the editor from the launcher and the viewport camera started to fall.

Yes, i tried with the c++ puzzle game from scratch, touched nothing, compiled it, launched the editor, boom, the camera started to fall.

I will let you know if the problem occurs again for me.

A precision i just remembered: when the problem occured, the camera was falling using its editor-defined-camera-speed (upper right icon in the viewport). When set to 1, the falling was almost unoticeable, when set to 4 it was falling fast.

It was really like if i was pressing the down key. I thought about a keyboard problem, but the “a” key i am using for down didn’t seem to have a problem in text editors.

oh yes ! I didn’t think about it, this really could be the cause of it for me.

By chance do you have a controller plugged in as well that could have a slight tilt in the control stick?

My controller was indeed the culprit, despite there not being anything pushing against the sticks. Strange.

Nicely done Sherlock :slight_smile:

Thanks and sorry !

Haha I just ran across this problem. It turned out to be the flight stick I have been using for Elite Dangerous. The default layout caused the the falling. Thanks !

Yes! Finally! It’s a stupid problem, but this happened like 4-5 times to me, now I know what the heck was going on :stuck_out_tongue:

Had the issue with the “falling camera” here as well. Turning off “Level Editor joystick Controls” in the Viewport Preferences helped me.

Immediate fix: inspired by comments above. Unplugged my gamepad and restarted.
Seems to be an issue with the way ue4 reads joystick/gamepad input.
