HELP PLEASE | ADK crash when re-targeting Raptor animations

Hello,

Whenever I re-target animations from a Raptor to a new skeleton (Raptor), the ADK crashes with the message:


Assertion failed: InSkeletalMesh->RefSkeleton.GetNum() == SourceAtoms.Num() [File:H:\SVN_Ark\Engine\Source\Runtime\Engine\Private\SkeletalMeshComponent.cpp] [Line: 854]

In the past, I’ve done this numerous times without any failed attempts and it works as intended with other creatures I’ve tested (e.g. Rex). So far only the Raptor gives this issue.
I’ve already tried both verifying and re-installing the ADK, but the problem still persisted. Both done via the Unreal Launcher.

Could someone please tell me what to do in order to fix this?

Thank you kindly,
Ennylia

I just tried to re-target the parent animBlueprint for the Griffin and received this error as well. I’ve already done this re-targeting process on the Argentavis’ parent animBlueprint and it works fine, so I don’t see why the Griffin is throwing this error, or the Raptor like @Ennylia says.

I’m mainly using this process to expose the parent’s graphs for editing, so if anyone has a better, less volatile solution it would be much appreciated.

EDIT: Just tried re-parenting a different blueprint to the Griffin’s skeleton and it still gave this exact error, so it’s an issue with the Griffin Skeleton. Perhaps a similar issue is causing the crash with the Raptor?
