Thanks, the cycle is now updated and indeed quite easy, thanks!

One questions:
I see that function GetDDescription is executed quite often.
So, I guess inserting the Cycle must be done somewhere else. For example in Init()?

PS one small error. The line "if not description.SetParameter(myCycleID, bcCycle, c4d.DescLevel(SWITCHFRAMESGROUP)) :" should have a DescID and not a DescLevel.

Look at the Message function and more specially about c4d.MSG_MENUPREPARE

Is that the only way to detect whether a different entry cycle is selected, or is there a message I can check.

Hello,

GetDDescription() is called every time Cinema is interested in the parameter description of an element. The edited Description it not stored anywhere so you have to define your custom parameter description every time GetDDescription() is called (since the parameter description can change at any time).

If you are interested when a parameter value changed you can implement NodeData.SetDParameter() or you can listen for the MSG_DESCRIPTION_POSTSETPARAMETER message.

So, now I can update the children in the Cycle field.

In the tag plugin, message() is used to get the value to define a new child of Cycle.
I add the input to a List, that is used in GetDDescription to define the children of Cycle.

However, how can I trigger GetDDescription to be executed, so the update Cycle is shown?

def Message(self, node, type, data) :
        
    if type == c4d.MSG_DESCRIPTION_COMMAND:
        if (data['id'][0].id == ADDCHILD) :
            data = node.GetDataInstance()
  
            child= data[CHILDINPUT]
	    self.children.append[child]	#used in GetDDescription to define the children of Cycle
            #now trigger GetDDescription  to show the updated Cycle
    return True

Hello,

you can make the host object dirty be setting the dirty flag DIRTYFLAGS_DESCRIPTION. That should trigger GetDDescription () again.

best wishes,
Sebastian

Thanks, it works if I set the tag to dirty using DIRTYFLAGS_DESCRIPTION.
