I am using a texture that I got from a height field output node. For simplicity's sake I removed my terrain shader and simply assigned a principled shader with texture displacement enabled. You can't really notice this unless the grid is really large (which it needs to be for me), but these grid lines appear in the render for some reason. They are not the edges/ resolution of the grid being deformed. I did notice that if I go to obj level and change the shading quality to a high enough value, the grid eventually disappears. Why is this? What weird is that these grids don't show if i render the heightfield directly.
