Hello, I have a question that I solved, but in a rather strange way.
I did this by copying new ones over the old points with offset by position.

Maybe there is an easy way to do this via vex. Or something else.

Hi,

If you already have normals, you can run this using a Point Wrangle (negative for moving inwards):

@P -= @N * ch("distance");

If the normal is not normalized, then normalize it also:

@P -= normalize ( @N ) * ch("distance");

Thanks and help!
@P -= normalize ( @N ) * ch("distance");
working.
For one axis.

Added a second axis, and everything works as expected.

vector up = {0,1,0};
@P -= normalize ( @N ) * ch("distanceX");
@N = cross(@N,up);
@P -= normalize ( @N ) * ch("distanceY");
