View Full Version : blendShape atts
11-23-2004, 09:02 PM
I need to list the attributes / the shapes in a blendShape node.
When I use "listAttr -k" I only get the envelope weight. Why?
Is there another command or flag I can use to list these attributes?
listAttr -m blendShape1.w;
hope it helps,

// find all blendshapeNodes
string $blendShapes = `ls -typ "blendShape"` ;
string $each ;
for ($each in $blendShapes)
string $attribs; clear $attribs ;
// find the targets (attributes)
$attribs = `blendShape -q -t $each` ;
print ("\n*************************\n"+$each+":\n") ;
print $attribs ;

listAttr -k -m works great... but I wonder what a multi-attribute is (as in -m)...

but I wonder what a multi-attribute is
I just had this same problem. Can anybody shed some light on why -k -m works? What exactly is a multi-attribute?
Any help would be appreciated. I hate scripting things when I don't know why they work.

A multi-attribute is an attribute that is not an array, but has multiple values. A good example is the translate attribute. Technically, it's only 1 attribute, but it has multiple parts, translateX, translateY, and translateZ.

translate is actually a vector-attibute not a multi-attribute. A vector has only three values but a multi-attribute can have as many as you want (just like the input on a plusMinusAverage node). Looks just like an array to me?
Vector can be made from the add attribute window, but a multi-attribute can not. To make a multi-attribute:
addAttr -m -ln myMulti -at double -k 1;
setAttr ".myMulti" 2;
setAttr ".myMulti" 3;
setAttr ".myMulti" 8;
setAttr ".myMulti" 7;
setAttr ".myMulti" 5;

Ok, so the blendshapes in a blendshape node are actually multi-attributes then?

Yes... It looks like the shape is connected to a multi-attribute inside of other multi-attributes; some strange things happening here:

Ok, this is making more sense now. This is why, when you add a blendshape to an existing node, you must specify an index.
blendShape -edit -target <baseMesh> <index> <targetMesh> <weight> ....;
So mult attr do kindof act like an array. They are arranged using the same 0-based indices.
