Overlay redux problem

Hi! I'm using the overlay redux extension but at the start of frame, even if I have no condition, the extension is destroyed... Why?

An MFA would be nice. Besides... :)

Here is an MFA, A or Z to launch a transition, and you can test, if the Overlay Redux is out of the frame, it's destroyed, an it's the same if the extension isn't in the scrolling of the frame.

Moreover, I want to make an ellipse transition as you can see in my MFA, is it possible with surface object? Because I don't know how. :/

My problem is resolved, thanks to surface objet, and thanks a lot to you Looki! :D
