I get this error, and haven't been able to find the source of it. Is it way
Python interprets the numbers for Y & Z?
# RuntimeError: setAttr: Error reading data element number 1:
[(24.1303752966691, 1.4210854715202004e-13, 5.329070518200751e-15)] #
Here's the method that generates it:
def FKstretch(self,limb,side,ctrlAttr,rigJnt,axis):
# create attribute
mc.addAttr(ctrlAttr,ln="stretch",at="double",min=0.1, max=3, dv=1,k=
True)
mc.setAttr(ctrlAttr+".stretch")
# get primary axis length value
jntLength=mc.getAttr("{0}.t{1}".format(rigJnt,axis))
setFkMdn=mc.shadingNode("multiplyDivide", au=True,n="{0}_MDN".format
(ctrlAttr))
mc.setAttr(setFkMdn+".operation",1) #set to multiply, just in case
mc.setAttr(setFkMdn+".input1X",jntLength)
mc.connectAttr(ctrlAttr+".stretch", setFkMdn+".input2X")
mc.connectAttr(setFkMdn+".outputX",rigJnt+".t{0}".format(axis))
The strange thing is that this method works perfectly fine when called by
the legs joints, but not by the arms. The code is identical for both.
thanks
