Convert Channels To Keyframes

[Lyonz]

Hey All,

Wondering is it possible to convert channel referenced animation to keyframes ? As i am driving a fan in dops by referencing animation created in sops but is not updating the position when simulating.

Cheers

Hi Lyonz,

I have had a same problem then I made a script.

Just put this in new shelf tool then push the button

sel = hou.selectedNodes()

parms = sel[0].parms()
keyedParmList = []
parmNames = []
for i in parms:
    if i.isTimeDependent() == 1:
        keyedParmList.append(i)
        parmNames.append(i.description() + "(" + i.name() + ")")

bakes = hou.ui.selectFromList(parmNames, message='Select Parms to bake key')

framerange = range(int(hou.expandString('$RFSTART')), int(hou.expandString('$RFEND')) + 1 )

for i in bakes:
    keyVals = {}
    for kf in framerange:
        keyVals[kf] = keyedParmList[i].evalAtFrame(kf)

    keyedParmList[i].deleteAllKeyframes()

    for kf in framerange:
        setKey = hou.Keyframe()
        setKey.setFrame(kf)
        setKey.setValue( keyVals[kf] )

        keyedParmList[i].setKeyframe(setKey)

Thanks,

Ryoji

I'm pretty sure, there is another, more procedural way of doing this. Try to figure out, why dops didn't updates correctly. Perhaps "Set Always" should be set on some data....
