texture

Hi, I'd like to confirm something with you. In the map file I received, the water texture in this area seems to be completely missing—I can't see any water. Is this normal? 

If not, how can I restore the texture? What steps should I take? Thank you!

Good afternoon, the developers have made new water, now it is influenced by topology, if water is the ocean, the ocean topology is needed, if it is the prefab of the lake, then the topology of the lake, I hope you will understand, I will not be able to explain in another way. I'm updating everything a little bit, there's a very large-scale update, because the developers are replacing the whole game in general.
