Textures on models messed up!

Hello everyone!
I am making a scene, and I imported some models in it, everything was fine, but suddenly, I see that some textures on some models are messed up. I don’t know what the problem is, I mean, It was all good before. Here are the pictures:

Someone has any idea how to fix it?

Find your texture file(in the Project window), click on it so you can see its details in the Inspector window. Look at your “Wrap Mode” setting and make sure it says “Repeat” not “Clamp”. On clamp it will display one line when tiled then stretch the last line on pixels over the rest of the mesh that it’s applied to, with repeat it will tile properly across the whole mesh.
