Solved "Current Take" doesn't override layer processes that made by scripting


I change layer properties via script and I need current take override those layer processes. But when I changed a property via scripting current take can't see any changins and does not override any data.

How can I do that?


hi and welcome to our forum,

For your next threads, please help us keeping things organised and clean. I know it's not your priority but it really simplify our work here.

I've added the tags and marked this thread as a question so when you considered it as solved, please change the state :)

About your question the take system is not automatic for scripts.

You can have a look at our example in python
Using Autotake
Other example about takes
How to create layers

Based on those example i came with this test that is working as expected. Using AutoTake. You have to pass to the function two object that will be compared.
So before doing the change, make a clone of your object.

But you can also write parameter directly on the take itself. (see above links)

import c4d

def main():
    rootLayers = doc.GetLayerObjectRoot()
    if rootLayers is None:
        raise RuntimeError("Failed to retrieve the Root Layer.")
    layer = rootLayers.GetDown()
    if layer is None:
        raise ValueError("layer is None")
    layerClone = layer.GetClone(c4d.COPYFLAGS_0)

    # Changes the radius of the sphere in scene
    layer[c4d.ID_LAYER_VIEW] = False

    # Gets the TakeData from the active document (holds all information about Takes)
    takeData = doc.GetTakeData()
    if takeData is None:
        raise RuntimeError("Failed to retrieve the take data.")

    # Checks if there is some TakeData and the current mode is set to auto Take
    if takeData and takeData.GetTakeMode() == c4d.TAKE_MODE_AUTO:

        # Retrieves the active Take
        currentTake = takeData.GetCurrentTake()

        # If there is an active Take, automatically generate a Take based on the difference between op and undoObject
        if currentTake:
            currentTake.AutoTake(takeData, layer, layerClone)

        # Pushes an update event to Cinema 4D

if __name__ == '__main__':
