Extruding Hex Grid Normal to Surface

Hello all, I am trying to get an extrusion that is normal to the surface. I have evaluated a hex grid onto the surface, but when I try to extrude using the evaluation component it creates what looks like 10+ separate extrusions all onto of each other.

Hello Lucas, the reason you get more hexagons is because you have 60 hexagons, but you are applying 360 transformations (I.E. a transformation for every point of the hexagon).

You need to apply 60 transformations for 60 hexagons.

I fixed your file. Let me know if it's good.

Yes! That's perfect, is it possible to move it based on a number slider? I realize its taking the vector parameter information and distance from surface evaluate, but I would like to potentially make this a little more parametric if possible.

Yes you can use a number slider. Hook up the N to a vector amplitude component along with a number slider.
