Evaluate Surface not preserving centroid

I could use some help here if anyone is feeling charitable. I can not seem to get the centroids to line up for the grid, and then the attractor elements. Hexgonal Grid Mapped Test.gh (13.6 KB)

Try merge two Hexa sets together for proper value remapping…

Wow… I love how simple that was. Thank you. Can you or anyone explain why merging the trees preserved the alignment?

Thank you again Kim!

When remapping two grid coordinates separately, the center of hexa cells will never match because each range values of the source domain are remapped to the same target domain.
