The only class you need is a BP based on the TaggedActor BP
There are two examples available from Lyra: B_Quinn and B_Manny. We reuse copys of these for our new characters - depending of we use male or female designs
The ABP retargeting process is easy now, using the ABP_UE4_Mannequin_Retarget via rightclick/”Retarget Animation Assets”/”Duplicate and Retarget Animation Assets”
Steps (referring to infographic letters)
J-K: Open the “Duplicate and Retarget Animation Assets” window, select your OK Retargeter and your new skeletal mesh as target to create an new ABP
I: copy either B_Manny or B_Quinn as your new TaggedActor BP and set it to your new ABP and the imported Skeletal Maseh
E: Update your CharParts BP
