How would you make these hexagons?

[thinsoldier]

Notice that a wall that is not shared with another cell is the same thickness as one that is shared.

To get that uniformity requires overlap/interpenetration

and that causes Z fighting

But because the overlapping faces are not mathematically perfect, because I positioned these by hand, Cycles does not have a problem rendering them. If they were perfect, cycles would have a problem with that.

But even without the face overlap z fighting issue, I want to use Subsurface Scattering, which has its own problem because of the shared walls.

I suspect that there are probably many fancy ways, that I don’t want to find out about so I would just make a hexagon:

I would duplicate it however I want in edit mode with snapping and merge by distance:

Extrude up and use Solidify in complex mode:

Sorry, I only noticed it’s about geometry nodes now. But can you really blame me? You are not showing any nodes…

Start here?

Hope that helps
