Hi Robert, thank you again for your reply. I will try to do it with a custom callback as you suggest. Let's see if I can manage to get the behaviour I want.

You can nest transform nodes and attach a seperate callback to each one, but this may well not be what you are after. "concatenate animations" is such an open ended term that only you really know what you are after. > I have also two more questions about animation: > > - What is the addNestedCallback function used for? The OSG doesn't use a concept of pre and post traversal callbacks for each of the different traversal but instead uses a scheme where multiple callbacks can be nested within each other. The advantage of this approach is that it makes it much easier to manage local state in a thread safe way and to control traversal. > - Is it possible to have different animations attached to the same > node and play only one at a time? The AnimationPathCallback doesn't support this but there is nothing to stop you from implementing your own callback to do this, or assign different paths at different times. Again I'd encourage you to roll your sleves up and code youself a custon update callback to do the animation exactly the way you need to.
