Init ( const TArray< FSoftSkinVertex >& InVertices
)

 Init from another skin weight buffer
Public function void Similar to Init/ReleaseRHI but only update existing SRV so references to the SRV stays valid
Public function void Should only be called for legacy meshes or meshes that don't really have a LookupVertexBuffer, for example created in realtime.
