This C++ Function is found inside of [[CAdditionalVertexStreamManager]].

It creates additional stream info.

It can be found in '''Client/Client Core/Sources/CAdditionalVertexStreamManager.cpp''' in Visual Studio.

==Required Arguments==
*'''state:''' To be defined.

==Returns==
Returns --to be defined.

==Code==
