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"

Particle emitters cause editor to crash

Hello. Whenever I try to view a particle emitter in the editor at any time it crashes. For example, if I double click on the p_explosion particle, it seems like it tries to load Cascade, but it then locks up my computer and the editor crashes. If I try to drag it onto the scene, that also causes a crash. Finally, if I try to spawn emitter in the scene using blueprint, it crashes.

As I mentioned in the duplicate question that was closed, this only happens for 4.4.1, not 4.3.1. Particles in 4.3.1 work perfectly.

I've tried to upload both the log and dmp files but the attachment tool keeps telling me that the file type is not allowed. Is there another place I should be uploading these?

avatar image Lovecraft_K ♦♦ STAFF Sep 10 '14 at 06:22 PM

Hey -

You should be able to put them in a zip file and upload the zip.

Thank You

Hey jeffym85 -

Can you also upload a copy of your DXDIAG.txt? You can get that by typing DXDIAG into the Windows search programs and files field, and clicking on the resulting icon in the Start Menu. If you have an ATI card can you also look and let me know what Catalyst Control Panel version number you are using?

Thank You -

Eric Ketchum

My Catalyst Control Center version is 2014.0417.2226.38446.

Hey Jeffym85 -

Can you try to go to AMD's driver support site and update to the newest version of the Catalyst Control Panel and Driver set, it should be 14.4?

Thank You

Eric Ketchum

avatar image jeffym85 Sep 16 '14 at 12:51 AM

Hi Eric,

The editor still crashed after updating my Catalyst Control Panel to 14.4. Attached are the new logs. link text

Hey jeffym85 -

I haven't been able to reproduce this crash internally here, but I am still experimenting.

Can you later today update your 4.4.1 release to the newest hot fix which should be 4.4.3 and test to make sure that you are still getting this crash, if so please one last time upload your crash logs.

Thank You

Eric Ketchum

avatar image jeffym85 Sep 17 '14 at 01:43 AM

Updated to 4.4.3 and still crashed.link text

avatar image Lovecraft_K ♦♦ STAFF Sep 17 '14 at 12:50 PM

Hey jeffym85 -

Can you try to close everything running in Windows then opening the editor and see if you can still get the crash on opening a particle system? You do not to reupload your crash logs, just confirm that it does still crash. Can you also confirm that this is any particle system provided with starter content you cannot open and have you tired to open the Effects level in the Content Example map?

Thank You

Eric Ketchum

avatar image jeffym85 Sep 18 '14 at 01:57 AM

It still crashed with everything closed. I have tried the content example maps and those don't work either. 4.3 works, but not 4.4

avatar image Lovecraft_K ♦♦ STAFF Sep 18 '14 at 01:35 PM

Hey jeffym85 -

I am going to have some of our engineers look through your logs but I want to give them some comparison logs from your CPU. Could you open a particle system or the Content Examples in 4.3 and then go into your project folder\saved\logs and upload those logs as well?

Thank You

Eric Ketchum

Looks like 4.5.1 fixed it. I can now bring particles in to my projects. Thanks for helping me through this.

Hey jeffym85 -

Can you try to go into your project directory before starting the engine and deleting the DerivedDataCache folder as well as the one found in /UE4/Engine/?

See if this fixes your issue, note that it will take a while to load the engine teh first time after deleting these folders as it rebuilds them

Let me know

Eric Ketchum

Still crashed. This is so frustrating.

Attached the logs. link text

avatar image Olaf Piesche STAFF Sep 23 '14 at 03:07 PM

Hey jeffym85,

Thanks for the info. We're still looking into the problem, thanks for your patience. As a workaround, one thing that could potentially work may be to make a copy of the emitter and try to add that to your scene. We'll be in touch with more information soon.

Thanks, Olaf

avatar image Olaf Piesche STAFF Sep 23 '14 at 04:55 PM

So, it's crashing inside of AMD's driver, but I'm unsure why as I can't seem to grab useful information from the dump file (it doesn't match up with our symbol information for that particular build, which is strange). I'll keep trying - in the meantime, could you try to run with -D3DDebug in the command line and post the log file here?

Thanks!

avatar image jeffym85 Sep 25 '14 at 01:40 AM

So I wasn't sure exactly what you meant with the command line. I tried two things: 1) I created a shortcut of the Unreal Engine Project File for my 4.4 project then added -D3DDebug to the end of the target. I then launched the editor by double clicking on the altered shortcut. The attachment Test1 shows the log file from that crash after I added an effect. 2) I opened the editor with the 4.4 project and hit play. I then hit ` to open the console in the game and typed in -D3DDebug. I then hit escape to get out of play and added an effect. Test2 attached is the crash report from that attempt.

I should add that the second time the editor did last a second longer than normal before crashing, but I still wasn't able to see any smoke from the effect when I placed it in the scene. Probably nothing, but thought I'd add it anyway.

Hey jeffym85 -

We still have not been able to identify why the AMD driver is crashing the engine, but I want to try some basic "fix all" solutions which might get you up and running.

First Uninstall the UE4 Engine and reboot your CPU if necessary

Second, Uninstall all AMD drivers follow the directions found here, http://support.amd.com/en-us/kb-articles/Pages/GPU57RemoveOldGraphicsDrivers.aspx#Win8

Third, Reboot your CPU if you did not have to after the second step

Fourth, Install the latest version of the AMD Driver, use the Automatic Detect and Install option found here, http://support.amd.com/en-us/download

Fifth, Once the new AMD driver and Catalyst are installed correctly and after any reboot that may be necessary, download a install the latest version of the Unreal Engine 4.

After all of that, please see if you are still crashing when opening a particle system

Thank You

Any progress on this? It's inhibiting many of the elements I want to add to my projects... and I'm paying $20 per month for it.

avatar image jeffym85 Oct 01 '14 at 03:16 AM

Did all of that and it still crashed. Attached is the new log.

Have you had other issues of this type from other users? Could it be specific to the r9 290 card? link text

avatar image Lovecraft_K ♦♦ STAFF Oct 09 '14 at 03:43 PM

Hey jeffym85 -

Are you having any issues with the graphics card with other programs? Black Screens when you play games on it?

Thank You

Eric Ketchum

avatar image jeffym85 Oct 12 '14 at 03:42 AM

No problems with any games elsewhere. Tomb Raider/Dirt 3/Sleeping Dogs etc. all work great.

avatar image Lovecraft_K ♦♦ STAFF Oct 14 '14 at 08:10 PM

Hey jeffym85 -

What is your card's (not the Editor) Anti-Aliasing settings? Are you running TXAA, FXAA, MSAA? Try disabling and see if you can then view particles. Also try disabling in the editor with a post process volume set to no AA.

Thank You

Hey jeffym85 -

Can you go to C:\Windows\System32 and look for the atidxx64.dll file and let me know what the file size is?

Thank You

Eric Ketchum

avatar image jeffym85 Oct 18 '14 at 01:37 AM

It's 10.5mb (10,573kb).

avatar image jeffym85 Oct 19 '14 at 10:41 PM

By the way, the program crashes constantly, not just when I bring in particles. There seems to be no rhyme or reason to the crashing either. Just now, it crashed while I was importing a static mesh. Attachedlink text is the callstack.

It actually won't let me import it at all. It just crashes every time I hit import. I attached the FBX just so you can check to make sure that's not what is actually causing the crash. link text

Hey jeffym85 -

With this latest crash I can at least tell you it is an error with the new Automatic Unwrap tool. I have submitted a bug report on it and will let you know as our engineers look further into the issue.

Thank You
