Hello,

I have a small test project.
Animating elements that move from point a to point b.
I need them to occure in specific time and disapear in another time.
Thhey all move from point a to point b.
I was able to make animation but i cant remember what node to use to make them disapear or occure.

Delete SOP?

On the Geometry object itself, there is Display parameter which you can animate, if you only require per-object visibility animation.
