    When I have two objects next to each other, there is a white line between them. How do I fix this? I have already tried disabling Anti Aliasing but that has not worked. By the way, I'm very new to Unity so I may not understand a few of your solutions...

    I feel like an absolute genius - I fixed it by myself after looking everywhere and finding nothing!

    I basically set the Texture Type to 2D (Sprite and UI) and set Extrude Edges to 0 on my PNG file. Very proud of myself. :)

    Weird. I just changed it back to 1 and the bug is not there anymore.

    Looking closely at the screenshot you posted I noticed there's a line in this image too:

    To me that makes me think there's probably a very thin 1 pixel outline in your texture, maybe a small amount of unintended transparency. If you scaled these up or down in Photoshop, it likes to ever so slightly blurred opacity in the edges of your layer which when imported into Unity will cause there to be a slightly white edge to your textures (blame Adobe, according to them this is the "correct" behavior).
