When I move the camera to certain positions, the edges of some textures show up in lines across the screen. Is there some setting I need to add or something? Any help is appreciated.
Use Pixel Perfect Camera on your Main Camera and also create a Sprite Atlas and add the tilesets to it (Unity - Manual: Sprite Atlas properties reference).
The problem goes pretty deep into how textures are sampled, but to fix this just add them to the Sprite Atlas and make sure it has some padding. Note that this only works at runtime, in the Scene view it’ll still look like this.
