Hi babylon team,
Correct me if I am wrong. My understanding is the noise is mostly based on the world position of vertices. There are some other input parameters, but as long as I use the same material instances for multiple tiles, the y values (noise) should be the same for vertices from two tiles but at the same x and z.
The following PGs seem to confirm my above assumption:
2 rectangle mesh tiles: Babylon.js Playground
2 hexagon mesh tiles. Custom mesh by using the positions and indicates from the hex mesh used in the NME video: https://playground.babylonjs.com/#RWHHBJ#2
However, I have my own custom mesh for hexagon that I can configure the subdivisions. When this node material is applied to this mesh, different Y positions for two different tile.
This doesn’t seem to be T-junction problem because the adjacent edges have the same number of vertices.
So basically 2 questions. 1) Is my assumption correct? 2) If it is, what could be the cause of the gap between two tiles?
I hope there is something obvious you can point out. Otherwise, let me know if you need me to provide a PG for my custom hexagon mesh.
