Hello All,
For some reason my sprites have a weird white outline when aligned with another sprite. They repeat perfectly in PS and I’m only seeing this in Unity.
Is there a way to remove this? (Note: This is not a gap between the sprites)
Without more info, it could be a bunch of things.
Disable mipmap generation and make sure your texture doesn’t get rescaled by unity (select npot if it is npot and set it to maximum res). If this fixes it, it’s a texture filtering problem and we can look into it more closely.
disable MSAA antialiasing. If that results in individual white pixels between your sprites, then the (post-transform) vertices of your sprites are not aligned perfectly.
If you rely on shader based anti-aliasing, it may be a problem with that.

Thanks for the reply Mabulous!
I don’t believe I’m doing any of those things but I could be wrong.
Here’s a SS of the inspector:
Not relying on a shader either. Just using the default.
Anything stand out to you?
So what’s the actual resolution of the texture file?

The resolution is 1024 x 1080.
What happens if you make it 1024x1024
The same issue happens for 1024x1024.
Curious why you suggested it though
Filter mode: bilinear switch → no filter, does that make it go away?
if the software was doing a resizing it could have improperly filtered alpha into color/rgb and made a ghosting edge

Hey thanks for the response!
Unfortunately, switching bilinear switch → no filter didn’t resolve this 
the only other unity setting I can think of is the compression is doing something.
otherwise i’d check to make sure the texture has a perfect alpha, if you resize an image in Photoshop it can blur your alpha and then the alpha could be causing a small line of transparency
in fact try disabling the image ‘import transparency’
use an opaque material,
it goes away it is the alpha channel
or adjust your background image settings to something like bright red : see if it that bright red is bleeding through.
Did you check about disabling antialiasing as suggested as well? it could be that the vertices of sprites don’t match up exactly and you’re seeing a thin, anti-aliased gap. Otherwise it would also help us investigate if you could share the raw texture file you’re using.
That helped in my case. Thank you very much!
