how to Unstretch Material on Object on 2.8? I am trying to make a city with lights on windows. Here is what I have done so far:

I have my city and my material for the window lights, but as you can see the tower in the back has the texture strech all the way up, I would like to know if there is a way to "unstrech" it.
I have tried to check on the UV map but I found nothing.

Does Anyone have an idea how ot make this ?

Thx in advance
If you like to control the texture using the UV's you should change the 'Texture Coordinate' node to UV instead of GENERATED.
