Looking for a most effective way to do movement after the elipse

[Jaroslaw Kaminski]

So do I need to split Master null or Rotating null?

Look, I’m splitting master null, then parent layer to that splitted null layer – and animation goes even before this 5s moment.So basically it does nothing, the rotation is still provided.
It’s the same if I’m doing it at rotating null layer, so I just got stupid right now

Did you change the name of the layer in the expression?

Basically, the marked selection of rotating layer (1st do 3rd second of animation), is an example where I would like to have rotation active. In the rest of the timeline it should be inactive, but I can’t manage to do that. The rotating motion doesn’t want to stop.
I’ve edited file that you’ve send me.
