Gaps between adjecent sprite tiles

I'm currently working on a 2d block based building game.

Unfortunatly whenever I build a plane of blocks this happens:



As you can see the individual sprites are placed perfectly adjacent to each other in the scene view, but in the ingame view the game shows some periodic gaps between blocks that shouldn't be there.

Here a closeup of the issue:



I'm fairly certain the problem is the result of individual pixels being right at the egde between two sprites and thus not registering either sprite as fully "below" the pixel, but I'm not sure how to best fix this.

The sprites have "point (no filter)" as filter mode and the issue exists both in the preview window and for fullscreen builds. (though the frequency and position of the stripes will depend on the chosen resolution)

 

sometimes it can be caused by the editor and a windows resize fixe it like in this video @40sec
or maybe you need pixelPerfectCamera from package manager

Make a Sprite Atlas and put your sprites into it. That should solve your problem.

 

@PGJ Thanks, I'm still not completely sure exactly why, but that fixed the problem perfectly.
