Problem to create a mesh from a triangular grid of points

Hi everyone,
I am trying to create a triangular mesh. To do so, I have modelled a triangular grid of points.

I am connecting this grid of points to a Mesh From Points component but it doesn’t work properly. I think the problem comes from the U and V entries of the component but I am not sure. Does anyone have an idea ?

You can’t use MeshFromPoints where there are not equal number of points in every rows: (21.9 KB)

Oh okay I see ! Many thanks
