Cant save even an empty map in my project, help

Development Pipeline & Plugins

Havent been able to save new created maps in my Project lately and excisting levels may corrupt when saving. Issues in both 4.16.3 and 4.17. Seems like I have broke something in my Project. At the same time I can save levels normally in blank projects with only used plugins enabled.

Is the map saving related to visual studio. My Project is opening the old visual studio 2015 while the that working blank Project open the vs2017. Could it be related to this issue. Or when saving map does it matter if having game mode set with player pawn/controller/other. Could that cause some conflict if e.g. player pawn would have something wrong? There is no visible errors listed.

When trying to save empty map, the progress stays at 0% and memory usage goes 98% and disk gets heavy use. But nothing else happens.

Have tried to verify ue4 builds, reinstall visual studios, removed saved and intermediate folders.

Issues started around when using 4.17 first time. I tried to package demo of my Project and it wanted to me to install some vs2015 again even it was upto date already. After that have been going back to 4.16.3 and again 4.17 with same issues on both.

Very lost what is causing the map save issues. Having no ideas after battling with the issue for many days.

Any guesses are welcome too. :slight_smile: Cant wait to work again on the Project forward.

After accidentally saving map, the editor wont load without removing the map. Even if using map backup that should work, it wont load the editor wihtout crash. I am very lost what is happening.

And in editor getting crash if trying to open blueprint. Sent crash report with:

I managed to find faulty blueprint (moved blueprints away from Project folder and brought back one portion after each other). After removing it from Project, the maps dont seem to break anymore. Need to test more, but so far looks very promising again.

Hello SaOk,

I have a couple of questions about the issue you are experiencing.

  1. What was the functionality of your faulty blueprint?
  2. did removing the blueprint stop all issue you were experiencing?
  3. is this issuer occurring in the 4.18 preview for your project with the faulty blueprint in?

Thanks!

  1. It was one (or 3) of the 20 blueprints. Most of those were not used for over year. I believe it was my grenade blueprint(s) that spawned another blueprint KillBP to destroy affected actor. I had changed that KillBP to be empty of most of code/variables (since not using it anymore). After that got crashes when trying to compile the grenade blueprints after removing KillBP spawn. Those finally compiled but seems like somehow corrupted.

  2. I noticed that I cant still save new levels (e.g make new empty map using that VR example and save it) - the editor freezes with 98%memory use and heavy disk use. That happens if I have made the level while having Project map loaded. If I rename my Project map, which makes no map load at start up, then blueprints dont open (without freeze), but I can make a new level and save it.

  3. The project is 115Gb so not currently ready to test with 4.18preview. I will need to buy another SSD at somepoint to have more space to make clone. Also using many plugins that are not yet available for 4.18.

As additional note, I managed to package demo of my Project. Cooking and packaging both succeeded, but the Project wont start. Looking into that during next days. For some reason, there is no log created when the packaged Project crashes at start up. Will check my build settings. Havent spotted issues/errors during playtesting my Project in editor. Seems very stable and FPS is very smooth.

Hello SaOk,

That is an above average size for a project, I have a couple more questions about your issue

  1. What is the file size of your project’s content folder?
  2. Have you tried deleting your saved and intermediate folders?

The packaged demo size is 7.5Gb, content folder is 110Gb. Been trying to remove those folders but no effect. Also moved whole Project to use new uproject, but no difference.

Hello SaOk,

The issue you may be experiencing may be due to the large file size of your project. Does the issue continue to occur if you reduce the overall size of your project?

Thanks!

I will try to do some cleaning at some later point to see that. Else probably easier then to save empty level in another Project and then copypaste it for my main Project to decorate it.

Would that be connected to harddrive speed or available memory? Since having 32Gt DDR2400 and samsung evo 960 m.2 ssd with 100Gb still unused.

Hello again SaOk,

did this help resolve the issue you are experiencing?

11

I am bit too worried to do heavy cleaning yet, so the existing maps wouldnt get messy. But keeping that in mind. For now, I will just create level in another Project and copy-paste it for this main Project. Saving already existing maps seem to be stable.

I will time to time, clean unused assets away, but that could take longer time. Noticed that packed Project anyway only include the level referenced assets, which is very handy.

I will try again the issue in 4.18 once its released (and all uess plugins are compatible with it).

12

I noticed that I can save existing level as new name too. But e.g. creating new blank sublevel cause heavy memory use without never competing. Just getting progress bar that never go forward.

Hello again SaOk,

Were you able to reduce the file size of your project? Did decreasing the file size help resolve your issue?

Thanks!

Sorry, having hectic times to prepare game release for winter. Could be that I will do testing for this bug only after that. Worried that somethingn could break (references or structures).

Good news :), started to use 4.18(.1) and issue is gone. New map saved instanly without issues now. Even didnt reduce the file size.
