How to create the UAnimStreamable asset in Unreal?


We noticed Unreal has announced the streamable animation since UE4.23. To get started with it, we are trying to see if we can create the UAnimStreamable asset first in Unreal. But there lacks information to tell how to do it, we checked the source code, still didn’t get the way of how UAnimStreamable asset is created. If anyone has practiced this feature, and knows how to do it?

thanks a lot
