Hi ihavenick, Can you reproduce this in any project or only your current project? Does it happen every time? When did this crash occur, during which step of process? Can you provide a list of steps you take that leads to crash reliably? Please and attach crash log and dump file from this project after this crash. Thanks! ---

Hey ihavenick, This has been reported in this post: > **[Animation Retargeting Crash Video](https://forums.unrealengine.com/questions/125444/animation-retargeting-crash-video.html)** > > See video bellow for repo. Video Link For some reason animations just won’t retarget. This is using 4.5 stable version. Any advice or tests I could run? We entered a bug report (UE-4827) and I believe it has already been fixed internally. You can follow post above for updates on issue. Thanks for your report!
