Unfold or unroll SOP geometry using UV. Has anyone figured out how do this in SOPs? Basically translating UV coordinate of point to its world coordinates on a XZ plane, and vice versa.

if your UVs are on vertices use Split UV Seams from sop Tab menu, check Promote To Point Attribute
then or if uvs were on points to begin with use Attribute Swap SOP (Mode: Copy, Source: uv, Destination: P)

That did the trick. Thank you

How would that work in reverse , if additional geometry is added? Lets say an unrolled surface is scatterSOP with points then Copy To Points SOP is used to populate the surface. Then previously unrolled surface is rolled back to original shape. What I find is happening when Attribute Swap SOP is inversed is that added points are collapsed into same P as on original surface.
