I'm trying to use geometry nodes to scale up a duplicate mesh along each faces' normal to "thicken" up the mesh. This can be achieved manually by scaling a mesh with Alt+S (Scale along face normals).

This picture (green) shows what I'm trying to achieve through the Geometry Nodes (manually scaled along face normals): Scale Along Face Normals

Here is an example of why a simple transform won't achieve the effect I'm going for: Normal Transform

    $\begingroup$ Just to clarify, are you looking to scale along normals, or extrude along normals? $\endgroup$ May 28 at 0:22

  • $\begingroup$ what would be the difference to scale the mesh!? $\endgroup$

Is this it?

2 Attribute Vector Math nodes, and 1 temporary attribute to hold the offset.

enter image description here

'Scale' along normals might (strictly) be a misnomer... Solidify, Displace, and AltS all translate vertices along normals.

I use this setup combined with the geometry edge split node, but is it possible to scale the faces but maintain the position of the faces?
