I have the same problem…

Making a aux effector/pivot is simple because it’s just a FBModelMarker

# select the effector where you want an aux effector 
effector = FBModelList()

FBGetSelectedModels( effector )

aux1 = FBModelMarker(effector[0].Name + "Aux")

aux1.Show = True

aux1.Type = FBMarkerType.kFBMarkerTypeIKEffector

matrix = FBMatrix()

effector[0].GetMatrix(matrix)

aux1.SetMatrix(matrix)

Now the problem is connecting it to the rig :|
Dont know how to do this but I’m guessing it is trough the FBControlSet, which you can get like this:

char = FBSystem().Scene.Characters[0]

controlSet = char.GetSrc(0)

FBControlSet is inherited from FBPlug, so it has all the Connect functions.

Also there is a class named FBEffectorSetID which may be related to this issue? :|

Please tell me if you figure this out… I will report if I get it working

This is how to do it! :)

def makeAuxEffector():

    controlSet = FBSystem().Scene.Characters[0].GetCurrentControlSet()

    effectorDst = controlSet.PropertyList.Find("RightAnkleEffector")

    effector = controlSet.GetIKEffectorModel(FBEffectorId.kFBRightAnkleEffectorId, 0)

    aux1 = FBModelMarker(effector.Name + "Aux")

    aux1.Show = True

    aux1.Type = FBMarkerType.kFBMarkerTypeIKEffector

    matrix = FBMatrix()

    effector.GetMatrix(matrix)

    aux1.SetMatrix(matrix)

    aux1.ConnectDst(effectorDst)

makeAuxEffector()

works nicelly. how would I move its pivot then, so that the ankle rotates from the ball of the foot? I have tried using getvector and setvector to the IKPivot but that doesnt work properly. I have to some how get the pivot of the object i guess…

Replies: 1

I think that property for that is called IKPivot, please try.

Cheers

i tried that but it moves the foot with it. what i need is to move the pivot like if you go in pivot mode and move it manually.

strange, in 2010 I have created Aux Pivot for ankle, selected and runned this script

from pyfbsdk import *

lModels = FBModelList()
FBGetSelectedModels(lModels)

if len(lModels) > 0:

    IKPivot = lModels[0].PropertyList.Find('IKPivot')

    if IKPivot:

        IKPivot.Data = FBVector3d(30,30,20)

        print IKPivot

worked as expected.

so, here is how i create it. If i manually change the IK pivot the ankle effector moves oposite from the aux. same when i run the script you posted. The only way it works is by going into pivot mode and move it.

controlSet = FBSystem().Scene.ControlSets [0]

def makeAuxEffector(lEffector, lid, lname, lPlace):

lChar = FBSystem().Scene.Characters[0].GetCurrentControlSet()
effectorDst = controlSet.PropertyList.Find(lEffector)
effector = controlSet.GetIKEffectorModel(lid, 0)

laux = FBModelMarker(lname)
laux.Show = True
laux.Size = 350
#xlaux.Parent = lPar
laux.Type = FBMarkerType.kFBMarkerTypeIKEffector

lmatrix = FBMatrix()
effector.GetMatrix (lmatrix)
laux.SetMatrix (lmatrix)

laux.ConnectDst(effectorDst)

makeAuxEffector("RightAnkleEffector", FBEffectorId.kFBRightAnkleEffectorId, “R Ankle Aux Pivot”, “RightFootEffector")
