Materialeditortutorial.uasset fails to cook

I’m running off of the 4.13 branch of the github source. When I try to build with unrealbuildtool, during cooking it will stall at this point and never end. Deleting materialeditortutorial.uasset allows me to get past this point.

Hello,

I have a few questions regarding this issue:

  • Does this occur when attempting to cook a clean, blank project?
  • How are you cooking the project? Are you using any special commands?
  • Are you receiving any errors during the cooking process or is it just stalling at the same point every time?

Thanks

I haven’t seen it on clean blank projects. I’m not sure why my project is cooking /Engine/Tutorial/SubEditors/MaterialEditorTutorial.

Just File->CookProjectsForWindows.

LogPackageName:Error: DoesPackageExist: DoesPackageExist FAILED: ‘None’ is not a standard unreal filename or a long path name. Reason: Path should start with a ‘/’

Bump, the same issue as paul.jan725 . every time when cooking the “MaterialEditorTutorial.uasset” ,UE4 stop building the project. I have wasted a whloe day to wait it complete.

Hey OpsStudio,

paul.jan725 has been unable to reproduce this in a clean project. Have you seen this on your end in a clean project or is it only occurring in the project you are currently working in?

I haven’t been able to reproduce this at the current time, but I’ll continue to investigate to see if I can get the same issue on my end.

In the meantime I’d recommend removing that file if it is only causing you issues, as I wouldn’t imagine it would have any negative impact.

Sorry , I just upgraded my project to 4.13 preview 3 today,so i can’t figure out the problem in preview 2.
Empty project with starter content have no this issue in preview 2 ,i checked out last time. with same contents can build success in preview 3.

Since it sounds like your issue is resolved, I will mark this topic as resolved. If the issue returns, feel free to return to this thread and provide updated information and I’ll be glad to continue investigating.

Have a great day

Hi Sean,
I post here because I had the same issue. Cooking hangs on materialeditortutorial in 4.13p3 (for hours, on two machines. tried to clean project from intermediate stuff and everything).
After a search I came here and saw there is no real solution. So I just deleted the whole C:\Program Files (x86)\Unreal Engine\4.13\Engine\Content\Tutorial directory. The build went through in a minute or two afterwards and runs fine. The project was migrated from 4.10 to 4.13p3.
I don’t need any help, I post this just as information. Maybe this helps others who come here and someone will find out why this happens.

Same thing here on same material when packaging ASTC for Android on 4.13.1 from Github downloaded today.

Edit: It happens that something else just caused an exception at the same time as materialeditorturoial is packaged as described in this thread. (In my case it was a create render target blueprint node in construciton script.)

Could you please provide the full repro steps that you are using when you’re experiencing this issue? I haven’t seen it occurring on my end as of yet.

Thank you

Hi Sean, I didnt try it again. But it happend when I wanted to test the new create render target bp node on android. I send u dl link for the project on forum.

A exception occurs somewhere in one of the render source files when you package this project for ASTC and Open GL 2.0

This error basically only occurs when you have a create render target node in a blueprint which is placed in a level i think. Not sure if anything else caused it… Its basically the same blueprint from the content example render level.

Hi spaceharry,

I apologize for the delay. Are you still experiencing this issue?

I have had a chance to test it and I’ve tried reproducing it in a clean project but I can’t seem to get the same results. If you are able to reproduce it in a clean project, please provide a detailed list of repro steps.

So i just came here to say that I am having the same issue with a 4.14 promoted build. It will just hang for hours (not failure, can still be cancelled) on both developer and shipping packaging:

UATHelper: Packaging (Windows (64-bit)): UE4Editor-Cmd: [2016.10.02-03.25.35:215][ 0]LogCook:Display: Cooking /Engine/Tutorial/SubEditors/MaterialEditorTutorial → E:/Documents/Unreal Projects/BrandMaker 4.14/Saved/Cooked/WindowsNoEditor/Engine/Content/Tutorial/SubEditors/MaterialEditorTutorial.uasset

Update I simply moved the Tutorials folder out of my source build content folder, packaged, then put it back and everything worked fine.

Do you have a set of steps that we can follow to reproduce the issue on our end? I’ve attempted to reproduce it in a clean project a few times but I have not been seeing the same hang that you seem to be experiencing. If you are unable to reproduce it in a clean project, the workaround of removing the tutorials folder during packaging seems to be the best bet for the time being.
