Hi Cameradan,
If you have anything that shows up in the “Timeline” as a track (e.g., Pos.Y), you can read out the value of that track with the node.
The time input of that node allows you to request a value from a specific time, which can be done with a fixed number or based on the time node itself.
In the example file I tried to make clear that “off-setting” the time is pretty simple.
It is certainly a nice idea to have a tutorial about, so many options with it…
All the best
Sassi
