Migrating UE4 Blueprints With Interfaces

[ZeothulBrian]

Upgrading to 4.25 removed the SteamVR Input folder from the engine because they replaced its functionality.

I was using the glove & hand animation assets directly from that folder, so I now need to migrate them from a 4.20 project to my 4.25 project.

I tried migrating an animation blueprint that references functions defined in handAnimInterface, but it breaks references to the functions defined by that interface when migrating.

Is there a better way to migrate that doesn’t break references?

I don’t know if you got your answer but I ran into the same just now. Figured out how to add the migrated interface like this → Implementing Blueprint Interfaces | Unreal Engine Documentation
