Hello! Sorry for English in advance. I am creating Mario Clone for learning. It won't be for commercial usage. It's only for learning how to create platformer games. You will understand my problem if you will see the picture below (you will see vertical lines): SuperMario_v1.2.0 (source) SuperMario_v1.2.0 (win)
You need to have some room ("padding") between the single tiles in your texture atlas. Textures tend to "bleed" over a little into adjacent textures.
How to make a handling of texture atlas to add the padding? What programs can I use? I have Tiled Map Editor, but I think it cannot.
I solved the problem. I will create little tilesets from the general tileset. For example by Paint and GIMP or by Tile Map Editor:
I solved the problem above. I apply this plugin and I wrote my own plugin for GIMP in Python.

I want to show you the solution again. Maybe you know a better solution. The problem (see on nose of bird): I solved this problem by this script and by my script. The solution is a new spritesheet:
Just so you know there is a fix for the problem you are having that is readily available inside Unity without additional software. blizzy gave you the answer (padding) to the issue. The fix to this problem is shown in the 2D section of the learning material.
