Hi,

I’m trying to apply a scale filter onto all curves in my scene. I got it working by applying the filter on nodes, but then it doesn’t make any change to the Ik effectors reach.
So what I’m thinking is too apply the filter on all FCurves, but I cant seem to find a way to get to all of them.

Any help?

Fastest way is to apply your filter on Model.AnimationNodes. Run this script while having selected IK with animatable Reach property and see results

from pyfbsdk import *

lModels = FBModelList()
FBGetSelectedModels(lModels)

def PrintNodes(pRootNode):
    print pRootNode.Name
    if len(pRootNode.Nodes) == 0:
        # here we have fcurve
        print pRootNode.FCurve
    for lNode in pRootNode.Nodes:
        PrintNodes(lNode)

for lModel in lModels:
    print lModel.Name
    PrintNodes(lModel.AnimationNode)

Other way is to find property and get animation node from it and then FCurve.

Cheers!

cool, thanks for the reply, I see what it does, but then I cant get the filter to work. No matter what I try. Either it gives me an error or simply does nothing.
I tried running the filter on both nodes and curves with no luck.

Oh, you mean, MB filter? Because as far as I remember, it require keys to be selected ? I think there were already a post about that...let me know.

I want it to apply a filter to all fcurves or animation nodes in the entire scene. skeleton, rig, constraints, etc.

I tried using these:

lFilter.Apply(FBFCurve pCurve)
Does not work. either gives error or does nothing.

lFilter.Apply( lModel.Translation.GetAnimationNode(), True )
This one I got working, but then I don’t get nodes that are other than translation, rotation and Scale. No reach T and R, constraints etc.

here is what I got so far. its loading for some time, no errors, but I cant see any change

lFilterManager = FBFilterManager()

def PrintNodes(pRootNode): 
    for lNode in pRootNode.Nodes:  
          
        if len(pRootNode.Nodes) == 0:
            # here we have fcurve
            print pRootNode.FCurve
            lFilter = lFilterManager.CreateFilter( "Time Shift And Scale" )
            lFilter.PropertyList.Find("Scale").Data = scaleFactor
            lFilter.Apply (pRootNode.FCurve, True)  
                 
        for lNode in pRootNode.Nodes:
            PrintNodes(lNode)

for lModel in FBSystem().Scene.Components:
    if "AnimationNode" in dir(lModel):
        print ""
        print lModel.Name
        PrintNodes(lModel.AnimationNode)

I am not very sure why you can’t use AnimationNode that I showed...so lets do it differently :)

from pyfbsdk import *

gFilterManager = FBFilterManager()
gFilter = gFilterManager.CreateFilter( "Time Shift And Scale" )
gFilter.PropertyList.Find("Scale").Data = 20
         
for lComponent in FBSystem().Scene.Components:
    if lComponent and lComponent.Is(FBModel_TypeInfo()):
        for lProp in lComponent.PropertyList:
            if lProp and lProp.IsAnimatable() and lProp.IsAnimated():
                gFilter.Apply (lProp.GetAnimationNode(), True)

Thanks KxL, it works. i just had to remove this one line.
if lComponent and lComponent.Is(FBModel_TypeInfo()):
