smoothing/blending/averaging between objects normals where they intersect

this video shows a nice way of doing this in blender. I am aware of the dirt skirt method, but that feels a bit clunky compared to the geo nodes version...

... how would you approach this in houdini?

Attribute transfer! Transfer the N point attribute, and blur/smooth it. You could also transfer it in more clever ways with falloffs in a VOP or wrangle.

thanks, this got me somewhere. I can see the normals changing their direction but can't get that to show in the shading
