I have a sword prop that I have created with a morth slider so I can make it as long or short as I wish this is working fine and as expected, but the problem I am having is if I want to make the sword "grow" over time.

I have looked in the timeline and used the collect clip to save the sword growing and select save to performance so I can select an action from the prop itself, but it is not saving the action so when I select the action from the performance menu nothing happens and I cannot see anything in the timeline.

Has anyone come across this issue or am I doing something wrong.

Cheers
Chris.
