Tile Map Tearing Problems

Thanks! This method really works You helped me from the trouble of redoing all my work.

 

I guess it's been a while since any updates on this thread, but it does include multiple solutions so at least one is bound to work. I just had the same issue and what worked for me was disabling the AA in quality settings, like Fariel mentioned:

To do this go to "Edit > Project Settings > Quality" and for every level of quality I disabled the Anti Aliasing. This fixed it instantly in the editor, didn't even have to build to double check.. but I did anyway

Let me add that my issue was not gaps between tiles but rather streaks of solid lines that may or may not show at random.

 

I have this problem for almost a week, already tried yours. It worked at first, but I forget to save the game, next time When I try to use this "New material" solution, it's just not working. Those lines don't pop up again but, more lines appear
Do you know how to fix those? still trying other solutions.

 

I think I just found a good solution for using dark textures reacting with lights !
/!\ This solution is only for those who use the Tilemap Unity system.

Just create a new material with the following shader : "Legacy Shader/Diffuse" (because the Sprites/Diffuse shader doesn't work).

And apply this material to your tilemap into "Tilemap Renderer".

This solution worked for me on my tilemaps. Fell free to ask me more precisions if you need it.

 

Hello everybody!!

Dealing with this problem I found out that the only definitive solution is putting a 2px padding in every tile. I tried everything and randomly happens in animations. It feels good to know that I wasn't the only one with this problem, I thought I was doing something really wrong

 

I might need to update my big list of fixes.

 

I found a solution using Unity's native tilemap.

After losing all the weekend looking for that Pixel Bleeding issue I almost give up using Sprite Sheet, but then I could understand better the cause of this problem and found a rather simple solution. It won't use any plugin or special coding.

In my case I'm using 16x16 block size and 1.1 camera size.

• - No Pixel Snap Material
• - No Manual sprite extrude and extrude edges 1 (sprite default)
• - Mesh type Tight
• - Sprite Atlas with Filter mode Point and Format RGBA 32

All I had to do was resize the tile by removing -0.0001 pixels both in X and Y.



This negative micro-pixel won't affect the visuals of any sprite and it will fix the pixel bleeding. I tested for an hour and the issue was gone.



This is barely noticeable and appears only in the corners, I noticed because I was using a pink bg to make sure I could see the line. Using a black background solve this or another sprite below.

 

Love your solution! Thank you

 

Hello, guys, I'm continuing the glorious necroing to add a solution that worked for me <3

Adding the spritesheet into an atlas seemed to have fixed the problem.
I started with a solution using the sprite packer (over there : https://nielson.io/2015/10/fixing-gaps-between-sprites-better-2d-in-unity-part-2) but this tool being legacy, now, I tried to find the replacement and found a video explaining the sprite atlas (

)

The documentation is here : https://docs.unity3d.com/Manual/class-SpriteAtlas.html

Note : I also used the pixel snap thingy (that's wasn't enough) and the automatic orthographic change wasn't fixing the tearing either for me (and I didn't want to use it anyway). Disabling all of these seems to be still working, leaving only the atlas.

 

This fixed it for me too. Thank you!

 

Great solution, this worked!

 

Honestly, just use a Sprite Atlas. It'll add padding that completely eliminates these issues without having to resort to such a hacky solution. In addition to that it also makes loading your assets much more efficient.

 

Sprite Atlas didn't work for everyone unfortunately (myself included). Only this trick works for me in that time, but now with Unity official "Pixel Perfect Camera", maybe this problem is not a issue anymore.

 

I thought you were using that already. Of course you need to use a pixel perfect camera, but in addition to that without padding you'll still get seems on some tiles.

 

In my case, the pixel perfect camera fixed all issues related to bleeding, but in Unity 2018 I'm still getting incorrect align edges in timemap "Composite Collider 2D" (something similar to ghost edges), and once more, this trick was the only way I found to a cheap fix. Using the Unity 2019 LTS, all problems are fixed in my projects.

 

More of a side note, instead of changing the sprites to have an overflow I changed the grid to have a tiny, tiny overlap. This was enough to fix my tearing issue at any resolution without needing to alter any sprites, imports, or workflow and did not have any constraints on resolution or camera.



While all solutions so far seem a little hacky(including this one) this seems to have the fewest drawbacks and least hassle.
