Scales on a snake howto - Fabrice - 02-15-2024

Hi all

I'd like to ditribute scales (a bent plane) along a snake body (a circle extruded along a spline).

But I cant find the right configurataion of the rotation node in order to get the scales to follow the body in a proper way.

Anyone has the solution of this enigma?

Cheers

I think I found something approaching setting the "surface element" to "From closest surface normal".
It is near the effect I was lookin for, the scales follow the spline's deformation.

But there are still some of the scales that are reverse (in red), 
I dont understand why?

Or Is there a way to delete those reversed one?
