Engine crashes after build when encoding textures

Development Rendering

Hello,

all of a sudden, I can’t finish the light building process anymore, since everytime it reaches the part where it says “encoding textures” it goes up till 40% and then i get the win error message that the program is not working anymore and needs to be shut down.

So far I narrowed the mistake down to this:

  • it only appears with this certain project, other projects work fine
  • it also happens on another system
  • it does not happen when I force “no precomputed lighting”
  • it does happen when I set all static meshes to movable

my specs:

Win7 Ultimate
Intel Xeon E5-2630
64GB Ram
Nvidia Quadro K4200

It basicly happend within an hour from working perfect to not work at all. All I changed was importing some meshes.

Pleas I need urgent help with this, I should render out a Video from this project tomorrow…

thanks

Lino

I think the file got corrupted because I hit the “save” button during the building process, could that be?

If yes it would be nice if the save option would be deactivated during the building to prevent this from happening…

Hi Lino,

When I attempt to save I don’t get the error you’ve described. Can you provide the full project log when the crash happened?

If this is only happening in your project and cannot be reproduced I don’t think I’ll be much help initially. You can try deleting the Intermediate folder from your project and see if maybe something in there got corrupted during this crash.

You can also try migrating all your assets to a new project and see if that resolves the persistent crashes with this particular project.

Beyond that, if you’re able to get some repro steps that can cause this to consistently happen that would be useful as well.

Thanks!

Tim

Where would I find the project log?
Deleting the intermediate folder did not work…still crashes
Is there an easy way to migrate everything? I have over 2000 Actors (It is a huge Project)

Project Log is located in Your Project Folder > Saved > Logs

For migration you can use the Right-Click context menu > asset actions > Migrate which just copies all the folders over. Alternatively, You could just copy everything in the Content folder of your current project to the Content folder of a blank project and all should work. When you open the project, it’ll probably take a little longer to load since it’ll need to write the DDC for the assets and compile shaders again, but should be a fairly seamless transition.

Unfortunately, there isn’t really much in the log to go off of.

Hello, Did you ever find the answer? I am having the same issue right now as well.

Unfortunately not, I think I migrated everything into a new project. (It’s already quite a whila go, so I don’t really remember fully)

It’s probably a hardware incompatibility at this point. I ran the project that was crashing on a similar system, but now on an i7, 32gb ram and nvidia quadro 5000, it worked like a charm. It just might the nvidia driver or the hardware, or even windoes server 2016 (that’s what i tested it on previously).

Any movement on this issue? I have the identical problem – the engine crashes while building textures. I get the error message:

Assertion failed: LCI->GetResourceCluster()->UniformBuffer [File:D:\Build++UE4\Sync\Engine\Source\Runtime\Renderer\Private\LightMapRendering.cpp] [Line: 49]

In my case, I don’t think it’s a hardware problem, since I have tried to build lighting on several machines, and I get the same error.

It tagged as an “old bug” but it is not . the problem is going on.
And unfortunately Unreal does nor give any clue what the reason on any log or stuff.
I am using Ue4.27 and the issue is there
