Heyho,

currently, I have a problem with the For each and sorting nodes.
I want some Alembic model sort over the Z-axis and then animated them from start point to end point separately with the timeshift upwards.

But I don´t get it working, probably something simple but I don´t find the issue.

I made an example for that and the file is attached, can someone help,

Thanks

Changed your sorting to primitives, and changed your last value from -12 to -20 in your expression of the time sop.(Loop block on the left)

Is that the effect you were after?

The foreach loop can be avoided in this case.

The animation offsets can be done in an attribute wrangle using the chv(parm, time) function signature.

I haven't found timeShift + foreach super intuitive (I feel like I have to re-learn it every time I use it. But in this case, if you are offsetting some animation, there are some attributes you can use for both packed prims and alembic packed prims, for offsetting time on different copies of an animated prim.

This odforce post links to the video + example: https://forums.odforce.net/topic/31923-arnesen-cubes-in-houdini/ [forums.odforce.net]

Hope that helps!
