Just a couple further questions for you so we can better investigate the issue that you are seeing.
I can assume the project that is causing issues has been migrated over to 4.2. Was it from 4.1 or 4.1.1?
When you migrated the project over, a box should appear asking if you want to open a copy, convert in-place, skip conversion, or cancel. Which of these functions did you happen to choose?
Last question I have is when you create a new project in your editor, if you run standalone or mobile and enter Show Collision, does the game crash then?
I tried this in VehicleGame and was successfully able to crash the Editor by entering the ‘Show Collision’ console command.
Before I enter this into our bug database, I wanted to ask you if this is happening on your own project or just in the marketplace downloads? I have found that the crash occurs in VehicleGame and StrategyGame. Just wanted to know if I need to add your project to that list.
I went in and put your bug/issue into our database so that it may be looked into. I am going to go ahead and approved this answer for tracking purposes.
i have the same problem in 4.7.6 - packaged project only, blueprint only, from blank project with some migrated assets from content examples such as the BP physics ufo. Would be nice for testers to be able to see collision…
Thank you for posting about your issue. I have attempted a quick reproduction of this issue and have been unsuccessful with seeing a crash. Would you be able to clarify if you would be packaging for Shipping or for Development? If the UFO asset is not in your project, are you seeing the same crash when using show collision?
If the crash does not occur when the assets are not in the project, would you be able to share the exact name of the assets that you have in your project that may be causing this error? Could you also attach your DXdiag?
Would you be getting any logs referencing this crash that you can share? You may be able to locate them using this pathing: >WindowsNoEditor>(Name of project)>Saved>Logs.
Any additional information would be greatly appreciated.
I believe i’ve isolated the problem. If i migrate SM_Cliff01 (from the Open World Demo Collection) to a blank Blueprint project and package, I’m able to reproduce with no other changes.
Thanks for the additional information. Would the crash be occurring once you enter the console command? I am getting a crash if I enter the console command, and the exit the packaged project. I just want to be sure before I write up a Jira ticket for this.
Above I had indicated “No other changes” I did, however, place the cliff mesh into the scene, save, and select that map for game default, editor startup, and server default in maps and modes in project settings.
Thank you for all of the additional information. I have been able to replicate the exact issue that you have been seeing. I have also attempted to reproduce this issue on both the 4.8 preview 2 build and out latest internal build and have no been able to reproduce a crash. It seems the error has been fixed since 4.7.6 has been released.
If you would like, you could test this in our Preview 2 build and see that the error is not occurring. I would not fully convert any projects to this preview build as our preview builds can be unstable, but you could open a copy and confirm this is no longer happening.
Please let me know if you do test this and still see any errors occur on your side.
