Hi. I have problems using tiles in Unity 2D.
As a wild guess, that might be due to the sprite’s border being exactly midway between an opaque and transparent pixel; the transparent side might still show on rare occasions.
You could fix that by shrinking the sprite’s border by at least 1 pixel on all sides, or reciprocally, making the sprite’s texture bleed out of their expected size by at least 1 pixel.
You should also set the atlas’ mesh type to Full Rect instead of Tight, this usually works better for such tiles.
Another guess – try turning off Antialiasing in Edit > Project Settings > Quality
Hi, the problem is still but only when the camera is moving. Any idea of what it might be?
Have you tried using a Sprite Atlas for your tiles? Try playing around with the Padding setting.
