Strange sprite artifacts on edges

I know this has been discussed over and over but i’ve tried all the solutions mentioned and none has been working. I somehow get cluttered effect on my sprites.

It’s photoshop file; sliced, 8x8 pixel wide sprites

Old post, but I’ll leave this here. First, on your sprites leave space between each sprite. Second, Create a material and set the shader to sprites/default. Then check the pixel snap option and throw that on your sprites.
