Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Lighting not rebuilding. SWARM: "Error: A 32 bit processes cannot access modules of a 64 bit process."

Hey, I got a message when in the PIE that lighting needs to be rebuilt, I clicked on Build -> Build Lighting Only, and after the Build Status box disappeared from the screen I launched again and noticed it still is giving me the message that lighting needs to be rebuilt. I opened up the swarm thing from the bottom right of the taskbar and this is the log:

 3:22:57 PM: Starting up SwarmAgent ...

 3:23:02 PM: [Interface:OpenJob] Error: A 32 bit processes cannot access modules of a 64 bit process.
 

Anyone experienced this or knows a solution? I just the engine an hour ago and am already running into this issue :/

EDIT FOR MORE INFO:

Branch: Binary Build version: 4.2.1-2101290+++depot+UE4-Releases+4.2 System: Windows 7 64-Bit. AMD FX 1600 (6 cores). 8GB RAM. GTX 650 (2GB VRAM).

There were "lighting building" messages on the bottom right when I was testing around projects earlier. In the FPS Blueprint template I was deleting the physics boxes that came with the default level, and I pressed Ctrl+Z to undo the deletions several times when the editor and engine crashed, and I submitted a crash report (Not sure if you can pull it up and see if this is related? There was this string in the msg: 38cd5001c824da7424b557ea6394ccd1 )

Uninstalled UE4, restarted, and reinstalled UE4. Issue still present.

The log above is when "Coordinator Remoting Host" = RENDER-01, I set it to my actual PC name "MATTHEW-PC" and the issue remains, but with this text instead.

 8:56:20 PM: Starting up SwarmAgent ...

I've attempted to enable Standalone mode in Swarmagent, did not fix anything, so I set it back to false.

I opened up SwarmCoordinator.exe myself and got everything connected and what-not, but the 32 bit error still shows up.

Any updates? Still have not been able to build lightning since I purchased the license and have been tirelessly looking for a solution.

avatar image Lovecraft_K ♦♦ STAFF Jun 27 '14 at 01:21 PM

Hi MattCan -

Originally are you trying to setup a Networked Swarm setup? And if so what originally are you using as your host PC for the Coordinator? Normally you should not need to set this up at all if you are building only using one PC. Agent will always attempt to start Coordinator to see if their is a rendering network, but that should not keep you from building lights on a single machine which it will default back to if no network is found.

Let me know -

Eric Ketchum

avatar image MattCan Jun 27 '14 at 01:28 PM

I wasn't trying to set up networking or coordinator hosting, I just clicked build lighting only in the editor and it outputted the first log above and that error.

avatar image Lovecraft_K ♦♦ STAFF Jul 01 '14 at 05:34 PM

Hi MattCan -

I have gleamed a little bit of information on what might be the problem with your Swarm Agent. To test this however, I want to make sure you have an absolutely clean no changes made to build of the engine. So, completely uninstall the engine (this should not remove your projects at all) and re-install from the Launcher Download.

Now, run Windows Update specifically looking for any Microsoft NET Framework updates and install them if any are found. Please make sure that the engine is installed before you run this update.

Test your Lighting Building Again on a new sample game type.

Thank you for your patience as we look into this issue and Let me know -

This is what I attempted to do yesterday however I get it all working but still get that 32 bit process error that's not letting it continue any further.

avatar image Lovecraft_K ♦♦ STAFF Jul 01 '14 at 06:38 PM

HI MattCan -

What version of Microsoft dotNet Framework do you have installed on your computer?

Thank You

Eric Ketchum

avatar image MattCan Jul 01 '14 at 06:40 PM

.NET framework 4.5

avatar image Lovecraft_K ♦♦ STAFF Jul 01 '14 at 06:58 PM

Hey MattCan -

Can you go into your C:/Program Files/Unreal Engine/Binaries/DotNET/ folder and zip all those files up (I do not need the sub-directories) and send them to me?

Thank You

Eric Ketchum

Filesize is larger than what I can attach to this so here is a Dropbox link:

Hey MattCan -

Are you running any firewalls or antivirus programs? If so, could you try to go in and add an exception for SwarmAgent.exe. Also ensure that you are running the engine with administrative privileges on your PC.

avatar image MattCan Jul 01 '14 at 08:45 PM

Running avast, disabled it and right clicked on the ue4 editor and ran as admin, same error.

avatar image MattCan Jul 02 '14 at 12:47 AM

Hey Eric, the issue seems really obscure. I've reinstalled Windows and no longer encounter this issue on a fresh install of Windows.

avatar image benox50 Jul 16 '14 at 04:33 AM

Same here

avatar image benox50 Jul 16 '14 at 04:43 AM

Purchased the engine and got the same issue, spending my afternoon on it, not fixed yet. It will be nice to know what version of the framework do I need cause It doesn't work with the 4.5.1 / 4.5.2 / 4.5 , no problem with the Unreal 3 SwarmAgent. The reinstallation of these framwork version does nothing for the moment.

avatar image Lovecraft_K ♦♦ STAFF Jul 16 '14 at 05:51 PM

Hi benox50 -

You are getting the same "Error: A 32 bit processes cannot access modules of a 64 bit process." message? If you have tried the updated framework, it might be a problem within the registry files or possibly a conflicting program like a Virus / Firewall program?

Thank You

Eric Ketchum

avatar image benox50 Jul 17 '14 at 05:51 PM

Yes, this one ''Error: A 32 bit processes cannot access modules of a 64 bit process'' , what version of the framework UE4 need ? The UE3 give you an installation of the framework 4.0, so at least I know the version it use. Now I only have the 4.5 installed on my PC, without it, the SwarmAgent just crash.

-Tried the firewall, but no -Tried the Framework cleanup tool and reinstalling Framework ver 4.5, this can be it, but no -Tried to revert from my registry of 2012, because I used Ccleaner and I was thinking that this may have changed the registry of the framework, good try, but no -Tried to reinstall wind... well, not now :X -Tried to use the SwarmAgent from UE3 with some files replacement, this was a desperate try and of course it doesn't work, of course I reinstalled UE4 after that -I was thinking of talking about that problem when I was buying some food, because the cashier tell me why I look grumpy today, but hey ! I dont think that would have worked too :p

avatar image Lovecraft_K ♦♦ STAFF Jul 18 '14 at 02:58 PM

Hey benox50 -

Can you let me know what version of the editor you are using? Also can you take a screenshot of your Swarm Agent Settings (Tab) panel and upload? (You should be able to open the Swarm Agent from \Unreal Engine\Engine\Binaries\DotNet\SwarmAgent.exe) If you cannot open this exe let me know that as well.

Thank You

Hey benox50 -

Thank You. So we know Swarm Agent is running correctly on your system. Let's see if we can get the NET Framework back up and connected again. Can you go to this website and use the Microsoft NET Framework Cleanup tool to ensure you have a correct build and installation of Framework:

Still same error after the use of the ''Microsoft .NET Framework Repair Tool'' same error too after the use of the ''sfc scannow'' cmd command

and no problem with the UDK SwarmAgent

this is the Framwork version I have on my PC :

Hey benox50 -

Ok, next step. Uninstall your Unreal Engine 4 completely. Your Project Files should not be affected. Make sure that you go into your install directory and completely delete any leftover files or folders after the uninstall. (So for me, I would check C:\Program Files\Unreal Engine\ - and make sure it is gone.) Then, go to your account page and re-download and re-install the unreal engine for scratch. Finally test your light building ability.

Thank You

For about two weeks I have the same error. It appeared out of nowhere.

I tried completely uninstalling the engine and .net framework (regularly as well as with the unofficial .net cleanup tool) and reinstalling both (first .net framework 4, 4.5 and 4.5.1, then UE4 4.5) like three times. I also tried the repair tool. Both without effect. "sfc scannow" didn't help either.

My Swarm Agent uses the default settings.

I'm out of options. I don't want to reinstall Windows just for this.

avatar image Jarek STAFF Oct 31 '14 at 07:48 PM

Hi DasMatze, I'm trying to investigate the problem, but unfortunately I'm unable to reproduce it. Could you help me with this?

It would be great if you could execute QAGame Editor, reproduce the bug on empty map i.e. try to build lighting and afterwards send me the contents of UnrealSwarm cache directory? It should be located in \UE4\Engine\Saved\Swarm.

Thanks, Jarek

avatar image Lovecraft_K ♦♦ STAFF Oct 31 '14 at 08:06 PM

Hey DasMatze -

You probably do not have access to QA Game Editor, so if you could try in the Third Person BP Template.

Thank You

Eric Ketchum

avatar image DasMatze Nov 22 '14 at 11:54 PM

Hi Jarek! Sorry for being late, I didn't notice there was a reply. I tried building the lighting in the third person template and looking for the cache (which is located at the place you mentioned, as the settings of the SwarmAgent say) but no files or folders regarding Swarm have been created.

avatar image DasMatze Dec 11 '14 at 09:11 PM

I looked for logs or anything related again and found something in the appdata folder:link text

I hope this helps!

The "Jobs" and "AgentStagingArea" folders in the same directory are empty.

avatar image Jarek STAFF Dec 12 '14 at 01:00 PM

Hi DasMatze, thanks for your help, but nothing special there that could point me at the problem.

If you'd like to help further it would be awesome if you'd replace your files with the one in the package I've attached here, reproduce the problem and resend me the log from SwarmAgent. Then we would at least know where in code it happens. The folder to replace files is in your \Engine\Binaries\DotNET.

Thanks in advance! Jarek

Thank you for looking into it! Here are both logs from the latest lighting build: link text (from Appdata folder as well as from the folder where UE4 is installed).

avatar image Jarek STAFF Dec 15 '14 at 11:13 AM

Thanks DasMatze, that helped a lot!

I still cannot reproduce this, but I found out a possible workaround for the problem.

Could you verify it?

The binaries are attached here. If you could replace them once again (same as before) and follow reproduction steps.

Hopefully it will help. If you confirm it I'll submit the solution and it should be in the releases soon.

Thanks for the workaround. Unfortunately I get this error in the log now:

  15:43:09: [Interface:OpenJob] Error: TestException
    bei NSwarm.FSwarmInterface.OpenJob(FGuid JobGuid) in d:\Perforce2\UE4-Releases\4.5\Engine\Source\Editor\SwarmInterface\DotNET\SwarmInterface.cs:Zeile 2007.

At least the message from the title is gone.

avatar image Jarek STAFF Dec 15 '14 at 03:01 PM

That's nothing. It's just debugging rubbish I've left in the first binaries I've sent you, but yeah it will block your tests. You can restore your backup (I forgot to mention that, sorry :() or use files from the file attached here.

It finally works again! Thank you so much! I was on the verge of reinstalling windows. I'm glad I waited.

i think the problems come from coordinator .I've used several solution to fix that. disable antivirus/disable firewall /repair dotnet and .... but it's not working.

we have some important project and waiting for long to fix this issue .. can any one help us. thanks.

using SwarmCoordinator on RENDER-01

Is your coordinator located at RENDER-01 machine? Maybe the name is different? Please verify it and fix in the SwarmAgent settings.

Thanks,

Jarek

Hi MattCan -

I am sorry you had to re-install Windows. We have tracked the issue down to an error in your NET Framework, which would have required a complete uninstall and re-install of that Framework, but we are still unsure of exactly what caused it.

Let us know if the problem returns -
