Flickering lines around images with transparency

Questions & Answers
1

I don’t know where to turn with this problem so im really sorry if its an easy fix (or if not!)
If you can see above my house on the right a line across the border of the image, ive been into photoshop and 100% made sure there is nothing but the line still shows in unity.

Ive done alot of tinkering, sometimes the lines would be less apparent when i stretched and shrunk a few of the sprites but i really cant be doing with that at all.

Can anyone give me any advice or help?

Thanks

That’s due to the type of filtering used on the sprites that are smoothing the pixels on the edge with the transparent pixels. This is especially annoying with sprite sheets when neighbor sprites will bleed the color/transparency into other tiles.

A few approaches to solve it would be to:

  • Use point filtering (that’s more for pixel perfect images)
  • ‘Bleed’ the pixels of the image border.

This might be a gizmo showing. Have you tried turning gizmos off? Even if you don’t, gizmos shouldn’t show up in builds so it’s not a big deal.
