- FVoidPtrParam now includes DataSize, and this is passed between functions to make it easy to know how big the void* Data is. - GetSerializedDataSize is no longer needed. Everything now uses the DataSize stored in the MetaData or returned directly from the Build function. #codereview Mikolaj.Sieluzycki [CL 2605033 by Geremy Mustard in Main branch]
