Reads Niagara Quaternion attributes by name from the cache frame and appends them into the OutValues array. Local space emitters provide data at local rotation unless bLocalSpaceToWorld is true. EmitterName - If left blank will return the system simulation attributes. LocalSpaceToWorld - Caches are always stored in the emitters space, i.e. local or world space. You can set this to false if you want the local Quat rather than the world Quat.
