Sprite's overlapping edges

Unity Engine
1

Hello guys.
I’m having an issue with a multiple sprite. Every tile is 64x64, and I sliced it with the grid function. So far so good, but the problem is that some of the tiles show the edge of it’s surrounding tiles. When I zoom in in the tile editor, the divisions seem perfect. Here, I have some screens for you:

First the tile editor window, when I leave a space between the line and the next tile, and how it works in-game

Now the same thing, but with the line exactly at the border

So, is it that the line in the editor includes the first pixels after it?

PS: Sorry for my english, it’s not my native language. Feel free to correct me.

Is not hte first line, this is an offset approximation problem, or also known as bleeding. One way to solve this as you did in the first pic, having some free space between sprites. Another way is to create a custom material using the sprite shader, and check Snap To Pixel option, still won’t solve it entirely, so make sure also that you have anti aliasing set to off.

Hi Neurological, thanks for your reply.
So I guess this is about mipmapping and upscalling/downscalling, right? Anyway, the Snap To Pixel didn’t work. Setting Filter Mode to Point semmed to do the trick, although it did become a little “blocky” as stated in the Docs. I guess I’ll just add one transparent pixel between all the sprites.
Thanks.

Been scratching my head with the same issue,

Thank you both for the insight! Will try out the suggestions too :slight_smile:
