Hi Robert, thank you again.
Then it seems that the only way to concatenate animations is by creating a custom UpdateCallback, right? Do you know any example about this that could help me to develop my own callback? I have also two more questions about animation: - What is the addNestedCallback function used for? - Is it possible to have different animations attached to the same node and play only one at a time?

One could write your callback that does this but you'd need to make sure that local and transform origins are all consistent. As I said in my previous email I'd recommend using your own custom UpdateCallback. This way you can compute the path exactly for each frame as per your requirements.
