How to make the correct rotation of a hexagon tile on spheric grid ?

Hi,

I have a rotation problem in my hexasphere project : I can't correctly rotate my tiles to generate a grid. I have to use "physical" tiles like blocks in Minecraft.

To generate hexagon tiles, i use a "sphere skeleton" and use vertices to fixe the tiles on them.

Can you help me to find a generic solution ? I mean I need a solution that I can use for the tiles of all layers/depths and correctly rotate the props on them too :)

Thanks for your help.

 private void GenerateTiles()
     {    
         Vector3[] vertices = this.GetComponent<MeshFilter>().sharedMesh.vertices;
         foreach(Vector3 vertice in vertices)
         {
             GameObject child = Instantiate( 
                 this.GetComponent<Planet>().tiles[0], // Tmp tile
                 this.tilesContainer.transform
             );
             Tile tile = child.GetComponent<Tile>();
             tile.body.transform.position = vertice;
             tile.body.transform.localScale = new Vector3(ratio, ratio, ratio);
 
             tile.body.transform.rotation =
                 Quaternion.LookRotation(-vertice.normalized) * Quaternion.Euler(0f, 90f, 90f);
         }
     }
