Animate points in 2d space, then return reapply to original position

[gangland]

Hello guys, I want to grab a deformed geometry, flatten in Y, do some point animation in the flatten area, then return the animated in 2d space to original geometry.

I did the flatten geometry, scatter and animated the points on it. But I have no ideia how to trasnfer them the to original position

Multiple ways to do this you could use the minpos, nearpoint, etc functions or use the ray sop for a non-code option.

You could also use the UV of the mesh (in other words you unwrapped the UVs, but in 3d space) do the scatter or whatever then bring back using the xyzdist function to find the closest prim, and the uv position within that prim.

Hi,

ray sop + primuv() or ray sop + attribute interpolate sop can do it
