Blending an art-directable hex chain into a global hex grid (topology transition issue)

[KTRS_Antoine]

Hi everyone,

I’m currently working on a procedural setup in Houdini and I’m running into a topology problem that feels more like a pattern blending issue than a simple modeling task.

 

I have:

• A global hexagonal grid covering a surface (regular and uniform)

• A chain of hexagons following a curve (custom shapes, scaled/oriented individually)

The hex chain along the curve is not arbitrary. It is art-directed and needs to stay fully controllable (scale, spacing, orientation, composition, etc.)

So I cannot simply regenerate everything procedurally or lose that structure through remeshing.

I want to Blend this art-directed hex chain into the global hex grid creating a smooth and coherent transition between the two.

What would be a robust procedural approach to create a clean and natural transition between both system ?

 

Thanks a lot !
