Hi guys!I am a beginner and I am confused by the Timeshift node. I want to know if my first animation ends at frame 20, and I want my second animation to start after frame 20, the expression would be $F+20? Thanks!

The frame in timeshift is the frame at which you want to evaluate the input geometry

So if you want the frame 1 to start at 21 then you need to use $F-20

Since then when you are at frame 21 it will evaluate the frame 1 (21-20) of your input geo

You can also use Retime SOP to do some common time manipulation like in your case Shift Range
