Level causing UE4.12 to crash (SEGV_MAPERR issue)

Development Platform & Builds

While working on a shared project, sometimes certain levels become unusable after pulling from remote and cause unreal to crash when the level is opened or on initialization when the project opens into that map. Not a programmer so no clue what’s going on so sharing the crash report here. Please help.

Additional info: this crash only occurs on my Mac, other team members using a PC do not have this issue.

3

Is this a Blueprints only project, or does the project contain C++ elements as well?

4

It’s Blueprints only.

Comparing the information with our crash data, I can confirm this crash is only occurring in the Mac OS environment. Hence, can you provide more information about when this crash occurs so that we can try to reproduce the issue on our end?

Also, please provide as many of the following as possible:

  1. Your Mac’s specs. You can find this in the Apple menu >About This Mac>More Info> Add the information from this window (serial # not necessary).
  2. The “System Report:” Apple menu >About This Mac > System Report>Hardware (All information listed in the “Hardware Overview.”) You can cut and paste this information or provide screen shots, whichever is more convenient.
  3. The UE4.log (Located: ~/Library/Logs/Unreal Engine/Editor/)
  4. The ProjectName.log (Located: ~/Library/Logs/Unreal Engine/ProjectNameEditor/)

don’t know why text the formatting on that post screwed up, here’s something easier on the eyes

Try the following:

  1. In the Content Browser, right-click the Contents folder and select “Fix-up Redirectors in Folder” and Save All
  2. Click on down arrow by “Build” in the Toolbar, scroll to the bottom and select “Map Check” fix all errors, ignoring Source Control and Localization Service, Save all
  3. (ONLY if first 2 steps DO NOT work…) Delete Intermediate, Saved, and Config folders from the project folder *Deleting the Config folder will result in having to re-enter your Project & Editor Settings

Hi ,

After comparing this with other crashes from our Crash Reporter site, the common denominator with machines reporting this crash is a reference to the HD5000 graphics driver. Please try updating this driver and let us know if does not resolve the issue:

Thanks,
