Hi, I am trying to make a 2D game in Unity3D. I did everything according to the tutorial on the website and it worked fine but when I tried to do the same thing in my own project I get the tiles appearing with seams like this. It appears both in scene and game view. I exported the project but it doesn't appear in the final product. It is quite annoying. Is there really any way to fix it.

I made sure I chose the extended option in sprite collection and I made sure that the camera and the texture has 100 as per meter pixel. I have 2 sprite sheets in the sprite collection. I tried deleting the object and recreating it. Not sure what else to do.
Thanks
