I opened one of my level and saved as a new level file, it was fine, but when I deleted the old map, the new map become like this:
Everything seems still there and selectable, what’s happening?
It’s months of works, and the deadline is tomorow… SO PLEASE PLEASE HELP ME! THIS IS EMERGENCY!
Looks like the z order is totally wrong, and the icons become flat, the blur is caused by the postproccess volum.
When see it in Unlit, everything looks transparent,like this:
And when i start a new level, it’s the same problem,.
All I did is deleted some old level maps,and Im desperated…
Could anyone help me?
Hi , thanks for answering.
The old map is not referenced by the new map, I simply save the old map as a new one, and did some changes, then use right-click menu to deleted the old map. When done, the new map just bcome like this. and even if I start a new map, things are still wrong.
Hi Nevets,
Unfortunately there isn’t much information to go on here.
Did you fix up redirectors before deleting the map? If you have a backup copy/source control. Revert to the previous version, then ensure you have fixed up redirectors before removing the map.
I opend the project in 4.11, Map Check found 3051 warnings,all says “staticmeshComponent … : Externally referenced”
No I do not have backups, the old map which I deleted were suppose to be the backup…
The source control is disabled. There are 90% assets are the same between them.
The map corrupted right after I deleted the old map, I didnt delete anyother assets in the CB.
Go to \Unreal Projects\PROJECTNAME\saved\backup, check to see if the .umap is there. Additionally, run "fix up redirectors in your content browser by opening the editor and right clicking the Content folder, then press “Fix up Redirectors”.
The umap is not in the backup directory, but fortunately, I find another way to recover it. I started a new empty project, and use it to replace all file in my project folder, then the “corrupted” map was recovered.
I don’t know how and why this worked, maybe I will find out some otherday. Right now I have to continue with my work, the deadline is 5 hours later…
Thank you !
I am happy to hear you were able to get your project going. If you get time and can do so, please upload a copy of your project here with what steps you took that caused this to occur, I’ll be happy to take a look and see if this is a bug or if there is some clarification we can make to help prevent something like this from occurring in the future.
WIll do! I’m glad I can help improving this awesome software!
Oh BTW, I remember now this is not the first time I meet this situation, when 4.8 preview is just released, I use it to open the 1st Person Shooter project which whas created with 4.7, and I saw the same strange scene corruption. I didn’t pay much attention cause it’s a preview version. Just thought should let you know this if anything helps.
Thanks again!
Hey I finally found what caused this.
It’s simply because I set the Project Settings → General Settings → Near Clip Plane to 0.
When I set it to any number > 0 and restart the editor, the problem is solved.
Could this be a bug? or was I just using it wrong?
I did more test on the Near Clip Plane setting, and here’s what I v found:
when < 0: everything is invisible, but you can still see then in wireframe;
when = 0: render wrong depth as I mentioned in the former post;
when > 0 but very small like 0.001: some stripes appear(shadow problem?)
when 0.01, the gaps between stripes age getting smaller.↓↓↓
when 0.1, looks normal. maybe the 0.1 is the smallest number for Near Clip Plane while it still works fine?
