Heya, this should be pretty simple but I can't wrap my head around.
I assembled a little test scene for show purpose.

The upper mesh (or lower) shall have the exact time and the copies of it should get x frames offset per step.

I used the copy stamp paramater only for random values in some tutorials. I am not sure how I can get a controlled output.
The For-each loop has the same problem. It bakes my time after every step.
(I guess instancing is also an option but I assume there's some knowledge needed which is too heavy for me right now.)

Are you trying to create a time echo effect? Why not use the trail sop?

Heya, thanks for your answer. I thought trails were only for computing the trails itself so that idea definitely helped but in this case I also want to offset the translation of each iteration.

Here we go
