v2.0

Creates an object representing the parameter's DataSource from file and connects it to the parameter. This method can be used to connect a Shader to a parameter from the shader preset file name.

Note: This method uses output arguments. C# and some scripting languages (such as JScript, PerlScript and Python) don't support arguments passed by reference. Normally for scripting you can get the output arguments via the ISIVTCollection, but this method already returns a value (C# cannot use this workaround because it does not have access to the ISIVTCollection).

The only available workaround in this case is to create a VBScript custom command which returns both the output arguments and the return value in one array. For details, see What Happens when the Function Already Returns a Value?.

The newly created object of a type based on the definition used, for example a Shader (see the DataSource topic).
