Ok, just realised the problem. It seems only SK_Head_HeadA and SK_HeadA_Bust has Morph Targets. It did not work in-game because I was using another head. How do I copy or transfer morph target to the ones that don’t have them?
SK_Head_Bust_LF and SK_HeadLF_Head only have a partial list. (only 7)
SK_Head_Bust_RF, SK_HeadRF_Head, SK_Head_Bust_RG and SK_HeadRG_Head all have no morph target at all.
Thanks!
