Blendspace crash

anon36098794 · October 26, 2014, 3:00am

I am updating my project from UE4.4.2 to UE4.5.1, and I have a blendspace with two animations. Well, when I try to edit it, by just clicking on one of those two animations little circle, on the graph area, it just crashed the engine.
The screenshot if from UE4.4.2, because UE4.5.1, just crashed again, and I opened the 4.4.2 version to edit the blendspace file there.

Hi ,

I’ve tried to reproduce your issue with a new project started in UE4.5.1 as shown here:

As well as by updating a project from 4.4.3 shown here:

However, neither case resulted in a crash. In order to better evaluate your issue, please provide the following logs:

the “UE4.log” Located: Engine\Saved\Logs\
…and the “ProjectName.log” Located: ProjectName\Saved\Logs\

Thanks

After all crashes, I submited the crash report, using the crashing reporting windows that appear when crashes happens. But, ok, i will collect those and send you.

Only log files that I found:

And here is a video showing the crashing. It happens all the time!

Hi ,

In order to help troubleshoot this further the developers have requested your call stack as well as the animation assets from the 4.5 converted version of your project.

If you could provide these it would greatly aid in pinpointing the problem.

Thanks.

Hi .

My call stack? kkk I don’t know what you mean.

Also, I just tried with a new UE4.5.1 third person BP project, and the editor still crashes, using the default animations and a BlendSpace 1D. So, this is not related to my project.
I added two animations and save it. Then I clicked on the smal animation circle icon, and nothing happened. Then I clicked on the other one. Nothing happened again. Then I clicked on the first one, again, and voilá. Editor crashed!

Hi ,

Sorry I wasn’t clear on how to obtain your callstack. When you experience a crash there’s a button on the crash screen that says “Copy callstack to clipboard.” If you copy that information and send it in a word doc it helps our developers compare it with other crashes to determine if this is an emerging issue.

I’ve also tried again in UE4.5.1 to reproduce a crash following your instructions. I’ve used idle/walk, idle/run, idle/punch, run/punch… when I click one circle button and then the other along the axis, the slider moves along with the mouse. Is this what you are experiencing? Also what are the two animations you are blending between? I appreciate any additional information you can provide.

Here is the callstack:

And here is a new video, showing a new ThirdPerson BP project. I created a new Blendspace 1D, and add two default animations Jump_loop and Jump_start. ( But this happens with all animations )

Then, I just click on the top circle button, and click on the bottom one, click on top again, and the editor crashes. Sometimes the crashing happens with the first click.

Thanks for providing your callstack as well as the additional video link. I’ve tried to recreate this problem precisely according to your video with no change in results.

Hopefully, the additional information you’ve provided will help the developers isolate why you’re experiencing this issue in which case this post will be updated accordingly.

Hi ,

Thanks for providing all requested information. With your help this issue has been fixed for a future release of the engine.

Having same problem for several days. Today I make a copy of my project and change engine version from 5.3.2 to 5.4.2, and that doesn’t happen for hours now.
