Artifacts on pixel sprites after slicing in Sprite Editor

I am slicing a 300x270 spritesheet into 30x30 grid slices to produce sprites like the following:



I'm noticing that in the Sprite Editor that it's not slicing them pixel perfect and it's including a little bit of an artifact on the bottom of the above sprite for example (his two feet):



When I then include this in my scene I see the artifact like this in game (see above his head? that's his feet from the sprite above):


I should mention the settings I'm using for the spritesheet before I slice them:

Texture Type: Sprite (2D and UI)
Sprite Mode: Multiple
Pixels Per Unit: 16
Generate Mip Maps: True
Filter Mode: Point
Max Size: 512 (my spritesheet is 300x270)
Format: Truecolor

Am I slicing these images correctly or is there something I'm doing wrong?

 

1. You are also probably using Filter Mode: Bilinear/Trilinear. Bilinear/trilinear filtering smooths the images. Try changing this to Point.

If this doesn't work:

2. You should add at least 1 pixel between edges of your Image. So, move your character so that there's at least 1 pixel between legs and lower bound of the slice.

I have so many spritesheets that moving them all to have 1 pixel between edges is ridiculously time consuming. Is that seriously the only way possible? Seems like a bug in Unity.

I also mentioned all the settings I've used for my spritesheets and Filter Mode: Point was one of them.

Thanks for your reply.

 

I had this issue and fixed it by slightly raising the sprite's position on the y-axis. I think it was something to do with how I placed the sprite in the scene on the ground collider. Maybe they were overlapping and causing issues.
