Sorry my bad,
When I was writing this my main goal was to get custom behaviours added then I remembered that timeline actions also do not transfer over.
I did a quick test to double check the timelines action and in the process some how did not get the timeline?.
Not sure what happened there. But I did not get the test timeline. Lets put that bit down to user error… and an addled brain… of cause timelines follow over
The actions definitely do not which are a big part of any animation
Scene actions also… yes please.
