As you see, the grass/rock and the water texture seems to repeat themselves (same waves, no variation, “tiled” look), making the whole thing look really unreaslistic.
I’m sure it must be fixable with a simple node, but I have no clue what I must do at the moment.
For landscapes I typically use a Landscape Coordinate node and adjust it’s settings accordingly. Alternatively for things like static mesh’s you can use a Texture Coordinate node.
This is an example of how I have my landscape set up.
