keyframes in python dont animate objects?

[katisss]

When i set keyframes in the transform channels with python it doesnt animate the object.

Am i missing something?

Can you see the keys in the graph editor? If not, then it probably isn't applying the keys properly. Below is a section of a script that sets key frames for reference.

    # Prepare keys for emission
    emissionKey1 = hou.Keyframe()
    emissionKey1.setFrame(startFrame)
    emissionKey1.setValue(0)
    emissionKey1.setExpression("linear()", hou.exprLanguage.Hscript)

    emissionKey2 = hou.Keyframe()
    emissionKey2.setFrame(startFrame + startPadding)
    emissionKey2.setValue(1)
    emissionKey2.setExpression("linear()", hou.exprLanguage.Hscript)

    emissionKey3 = hou.Keyframe()
    emissionKey3.setFrame(endFrame - endPadding)
    emissionKey3.setValue(1)
    emissionKey3.setExpression("linear()", hou.exprLanguage.Hscript)

    emissionKey4 = hou.Keyframe()
    emissionKey4.setFrame(endFrame)
    emissionKey4.setValue(0)
    emissionKey4.setExpression("linear()", hou.exprLanguage.Hscript)

    # Set keys for source emission
    amountParm = hou.parm('/obj/volumeSim/apply_source/scale')
    amountParm.deleteAllKeyframes()
    amountParm.setKeyframe(emissionKey1)
    amountParm.setKeyframe(emissionKey2)
    amountParm.setKeyframe(emissionKey3)
    amountParm.setKeyframe(emissionKey4)

thanks, Luke i check

hi,

i forgot about emissionKey2.setFrame(i)

thinking i could create the frame like emissionKey2 = hou.Keyframe(i)

Thanks for helping
