v7.0
Creates a DataSource
object from a preset name and connects it to the parameter. This
method can be used to connect a single output shader to a parameter
from the shader preset, in which case the Shader object is returned. It can also be used to
connect a multi output shader or shader compound to a parameter, in
which case the Parameter object
representing the connected source is returned.
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?.
oReturn = Parameter.ConnectFromPreset2( Name, [SourceName], Family, [PrevDataSource] ); |
The newly created object of a type based on the preset used, for example a Shader (see the DataSource topic).
| Parameter | Type | Description |
|---|---|---|
| Name | String | The name of the preset (see the list of Shader Presets) |
| SourceName | String | The name of the source (or output port) on the shader we want to create. Leave empty to connect to default output or for single-output shaders. |
| Family | siFamily | The family name of the preset |
| PrevDataSource | DataSource object | The previously connected datasource if any; Nothing is returned it there is not previously connected datasource. |
