    Is there a way to get notified when a object(camera) is deleted or renamed?

    from a coremessage method listen for EVMSG_CHANGE and then check the reference/pointer
    on your object if its none, its gone :) if it is still a GeListNode you can check the name.

    I have registered a MessageData-Plugin and get EVMSG_CHANGE in the coremessage function. I am storing a BaseObject * m_object somewhere in my plugin. How should I check my pointer m_object if it is none? I mean m_object doesn't get NULL'ed automatically when the user deletes my object.

    The EVMGS_CHANGE doesn't give me information about which object has changed or deleted, right?

    Can you help me?

    Store a BaseLink to the object instead of a direct pointer. It will allow you to check if the object
    does still exist or not.

    Ok. This works.

    But I still have to find out which one was deleted and which one was renamed all by myself instead C4D is doing this for me, right?

    I would expect that the SDK is doing this for me.

    Well, do you want to checl for a specific object, if it was deleted or renamed, or the whole hierarchy?
