Hi,

I’m currently experiencing frequent crashing in UE4 while trying to move/rotate a MetaHuman character with retargetted Mixamo animations. Each time it crashes, this crash log comes up with the same failed assertion command:

Assertion failed: RootLOD == MeshComp->GetPostProcessInstance()->GetRequiredBones().GetCalculatedForLOD() [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Engine/Private/Animation/AnimInstance.cpp] [Line: 2863]

Any ideas on how to fix/avoid this crash?

Not sure if it’s the right way, but had the exact same problem with same error code.

I set the LOD to a fixed number in the MetaHuman_BP, now it doesn’t crash anymore but I don’t know for how long it will hold up. Could be a quick fix, but since i can’t find anythin else online i thought i share it.

  • MetaHuman Blueprint> LODSync > LOD >
  • Set Num LOD 1
  • Forced LOD 1
