Why can't I retarget Animations

Whenever I try to retarger animations, UE4 crashes. Why is this happening, also is there any way to resolve this issue?
Any Answers appreciated.

Hi ,

We need more information in order to troubleshoot your issue:

  1. Are you on a Mac or PC?
  2. What operating system are you running? ie OSX 10.10.5 or Windows 7
  3. What version of the engine are you using: UE 4.9.2, 4.10Preview etc.
  4. Are you the Third Person Template or a blank custom map
  5. What animations are you trying to retarget to and from? For example, trying to retarget TO the UE4 Mannequin FROM Mixamo’s Adam.

Please provide this information and we will continue to troubleshoot from there.


Windows 10.
Third person template
Anim starter pack animations to ue4 mannequin

Also I’m running a 5700k i7 8 core cpu.
Gtx 970M 3 GB VRAM

Thanks for providing the requested information. I was not able to reproduce the issue by adding the Animation Starter Pack to a Third Person Template then assigning ASP animations to the Third Person Mannequin and vice versa by retargetting. Here is an image of the third person animations assigned to the ASP skeleton:

I am not sure why this would crash when they were built off the same skeleton. The only thing I can think of is, did you open both skeletons and set the rig to “humanoid” with the retarget manager before retargetting in the content browser?

Please review the following documentation on retargetting the same skeleton: [Animation Retargeting in Unreal Engine | Unreal Engine 5.1 Documentation][2]

Then respond if you are still experiencing a problem.

I did set it to humanoid
The message window pops up in the Windows taskbar but unreal engine instantly crashes.

Still having problems

Please download 4.8 and try it in that version of the editor. If you are still having problems, please send me your project in a private message on our via dropbox.
