That would be a bug. Softimage is suspposed to handle the conversion from Jscript array to SafeArray as that's how it's handled in the rest of the application.

Check out the code below for the conversion. - As a workaround for setting MaterialID, you can store the data in a custom attribute, then use ICE to read from it and set MaterialID function getSafeArray(jsArr) { var dict = new ActiveXObject("Scripting.Dictionary"); for (var i = 0; i < jsArr.length; i++) dict.add(i, jsArr[i]); return dict.Items(); } //to a safe array var safearr = getSafeArray([1,2,1,2,1,2]); //back to a js array //var jsArr = new VBArray(safearr).toArray(); cube = Dictionary.GetObject("cube") attr = cube.ActivePrimitive.Geometry.AddICEAttribute("CustomMaterialID", siICENodeDataType.siICENodeDataLong, siICENodeStructureType.siICENodeStructureSingle, siICENodeContextType.siICENodeContextComponent2D) attr.DataArray = safearr -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Stephen Blair Sent: Tuesday, March 12, 2013 7:29 PM To: [email protected] Subject: Re: setting ICEAttribute.DataArray in JScript Last time I tried, I gave up on JScript (it seemed impossible) and got something to work in Python. si = Application from win32com.client import constants as C # win32com.client.constants oObj = si.Selection(0) oICEAttrMats = oObj.ActivePrimitive.AddICEAttribute("MyString", C.siICENodeDataString, C.siICENodeStructureArray, C.siICENodeContextSingleton) oICEAttrMats.DataArray2D = ["a", "b", "c", "d"] x = oICEAttrMats.DataArray2D print x print len(x) print len(x[0]) print len(x[0][0]) for d in x[0][0]: print d # (((u'a', u'b', u'c', u'd'),),) # 1 # 1 # 4 # a # b # c # d On 12/03/2013 5:18 AM, Eugen Sares wrote: > Ok...
