Node material water looks triangulated, how to make it smooth?

Hi!

To make it work you have to recalculate all the normals inside the shader. I created a topic about that some time ago. So it could helps you:

How to smooth normals useing NME?

Your computations of displacedNeighbour1/2 is wrong in the NME, you should apply the displace transformation to neighbour1/2, not do neighbour1/2 + displacedPosition. This seems to do it: Note that I had to use an elbow node to connect the output of the (final) normal vector merger block to the transform block (to compute the world normal), directly connecting both would not work for some reasons…
