Help me understand the attribute expression sop

Recommended Posts

Posted (edited)

It's houdini 18

Displaying the attribute expression sop and playing it will cause problems.

1.
Based on the red value, I want to make the trail passing through the grid sink as much as ‘0.2’, but only the grid tilted by 0.2, and the trail remains unchanged.

2.
Why does the trail mark last longer than the reference geometry when the frame is played?

Tell me how to solve this problem.
