I had a problem with adding a CC4 character to the new Game Animation Sample pack. Following the official documentation caused crashes and the Post Process Animation Blueprint was disabled for an unknown reason. After a few attempts I discovered a process that allowed me to successfully add my CC4 character to the sample project.
Here is what I did:
- Setup IK Rig by copying the UE4 IK Rig and replacing with the CC4 Character.
- Make an IK Retargeter using RTG_UEFN_to{character-name} naming convention, set source to UEFN_Mannequin IK Rig and target to the CC4 IK Rig. Save and close.
- Add your IK Retargeter to the ABP_GenericRetarget array.
- DO NOT make a child blue print of the CBP_Sandbox Character
- Instead open up the folder with the Retargeted Characters and make a copy of the CBP_SandboxCharacter_UE4_Mannequin (or the Twin Blast one will also work).
- Rename the copy to your character and open it up.
- Select the SkeletalMesh that is a child of the Mesh Skeleton.
- Set the Skeletal Mesh Asset to your CC4 character and change the Component Tag to the name of the CC4 retargeter, compile and save.
Follow the rest of the official docs to add your character to the widget for selection. That should be it. Hope this helps.
