v1.0

Adds a property to objects.

Notice that UV cluster properties and vertex color properties can only be added to clusters which are always complete, see Geometry.AddCluster method.

Note: This command uses output arguments. C# and some scripting languages (such as JScript, PerlScript and Python) don't support arguments passed by reference so you need to use the best workaround for your situation:

For scripting languages this command returns an ISIVTCollection which you can use to get the output arguments.

For C# you can use the XSIApplication.ExecuteCommand method to call this command. ExecuteCommand packs the output arguments into a C# System.Object containing an Array of the output arguments (see Calling Commands from C#).

VBScript Example

'Example showing how two custom properties can be added with a single call to
'SIAddProp
SIGetPrim "Null", "FirstNull" , ActiveSceneRoot
SIGetPrim "Null", "SecondNull", ActiveSceneRoot
dim oCustomProperties, oCustomProperty
'Create a custom property under each null
SIAddProp "Custom_parameter_list", "FirstNull,SecondNull", , "Chain_From_Curve", oCustomProperties
'The return value is a collection of the newly created items
for each oCustomProperty in oCustomProperties
        SIAddCustomParameter oCustomProperty , _
                "nbJoints", siInt2, 10, 1, 1000, 8, 16, 1, 100, "Bones", "Number of Bones"
