Hi, that’s an oversight on our part from when UAnimSequence::PlatformTargetFrameRate was added. That replaced UAnimSequence::TargetFrameRate and we should have deprecated and hidden TargetFrameRate when that happened (we’ve since hidden it in subsequent versions). Nothing should be using TargetFrameRate so you should be ok to just ignore it.
UAnimSequence::PlatformTargetFrameRate should show the correct frame rate for your anim sequences - it gets set in UAnimSequence::OnModelModified:
case EAnimDataModelNotifyType::Populated: { PlatformTargetFrameRate = Model->GetFrameRate();
Let me know if you’ve got any questions on this.
