Hi,

thanks for your patience.

I was looking into the editor log file and did various tests with UMotion 1.19p02 in Unity 2019.1.8f1. Unfortunately I haven't been able to reproduce a crash and the editor log also didn't contain any helping information about the crash.

Please continue taking an eye on this issue and maybe try to find a way to reproduce this crash on your system. You might also try updating to a newer Unity version as it might be possible that the crash is coming from a bug in the Unity API (the managed C# code of UMotion itself shouldn't be able to crash Unity in theory, but calls to native code like the Unity API can).

Best regards,

Hi,

thank you very much for your support request.

Which operating system are you using?

When you say it crashes Unity, you mean that Unity closes without any error measage or do you get an error message?

Could you please attach the Unity editor logfile (after a crash happened).

Thanks.


Best regards,

Peter

I am using windows and yes there was no error message.


Editor.log

Thank you very much for providing the log file. Unfortunately I'm not in the office til August 28th so I can't do any deeper investigations til then.

Technically speaking in 99% of all cases only native code can cause such a crash. The only part of UMotion that uses native code is the FBX exporter (which is only involved if exporting an animation to FBX). So with saving the project you mean that you save the whole Unity project (i.e. click save in Unity) or are you exporting your UMotion project to FBX?

If you are not exporting to FBX, please try to double check that it is really UMotion that is causing the crash. As UMotion is written in C# (except for the FBX export) it should only throw exceptions in the worst case (shown as error messages in the editor) not crashing the whole editor.

Best regards,

Peter

I am 100% sure Umotion causes the crash. There is no problem when I am working with level designing or scripting. But when I start to animating it crashes unity frequencly. Sometimes rotating a rig but most of times saving the whole unity project. And the crash ignores the most recent save so I have to start all over again. Because of these crashes my 2 days job is now 1 week job. I need a solution as soon as possible. Also we all are developers here so no need to classical customer officer answers of any kind of product..

UMotion does automatic backups of your project which you can use to restore your work in case of a crash. Backups can be restored by clicking on the related menu item under Clip Editor's File menu. Please refer to the manual for further information.

Do you have some sort of minimalistic project that I could use to reproduce the crashes? As of now I have no reports of sudden crashes and haven't seen any myself so this might be an indication that the problem is related to some specific circumstance.

Best regards,

Peter

Unfotunatly I am working on a big project with umotion but I think the source of problem is versions. Because I udes umotion with another version of unity recently and there was no crash.

Ok thanks for all the information. As soon as I'm back in the office (August 28th) I'm going to try to reproduce this issue. Unfortunately I have no chance to look into this issue before that date. I'm sorry for that.

In the meantime, if you notice any further information that could help me getting this reproduced, please update this post.

Thank you very much and I'm sorry for the inconvenience.

Best regards,

Peter
