Hi everyone i tried since a lot of time to orient normal of points perpendicularly to his edge but as you can see on the screens the normals aren't perpendicular

in red you can see what i want to have, it's starting to drive me crazy

Hi,

Here is one way:

Create tangent vectors using PolyFrame SOP (Style = First Edge), then rotate the vectors around an arbitrary up vector:

matrix3 M = ident ( );
rotate ( M, radians ( -90 ), { 0, 1, 0 } );

@N *= M;
