The first step is to open the project and enable these plugins:
- “HairStrands” also known as Groom
- “MassAI”
- “MassCrowd”
- “MassEntity”
- “MassGameplay”
- “RigLogic”
- “LiveLink”
- “LiveLinkControlRig”
- “AppleARKitFaceSupport”
Then restart the editor and you will get a couple of mild errors. Navigate to the BP_CrowdCharacter by clicking on the errors in the Output Log window: You will encounter something around the lines of: ‘Depreceated get skeletal mesh calls’. I can’t reproduce what you will exactly get, but the beautiful thing is, that the editor will most likely tell you what to do in the Output log. In short: Hook two or three of these nodes to a new ‘Get Skeletal Mesh Asset’ call (again doesn’t have to be the same for you), compile and you will be good.
Good Luck
