I'm seeing what looks like a strip of black pixels across the very top of my images and odd lines here and there when doing animations as the spites flip in and out.
I've tried literally every combination of settings I can think of but nothing works universally.
What I have is 40x40 pixel art characters that load right into a tk2d sprite collection. I have the target height set to 126, tried 128... same results but at different resolutions. I've tried uncompressed, trim alpha on, off, reduced 16 bit... but no matter what settings I use depending on the device resolution I'm seeing extra lines drawn inside my sprite images. The web build I have seems to look perfect if i export to 1024x768 but if I try something like 1280x720 all a sudden I get the lines.
This is really putting a kink in our plans for a pixel art game so any help is appreciated. I created our previous game which had 100x100 images and had zero problems, so I don't know if it's because the target height is so small or what the problem is...
Edit: To confuse matters more I've removed all sprites from the scene so that there are none overlapping or anything else that might be causing issues. The black line of pixels or odd vertical ones, etc appear based on a combination of res and position on screen. Example is I can set up 4 characters with the same sprite on the screen with target size 128 and maybe only 2 will have the weird line of pixels, but if I move them all then all might have it or none. If I then change the resolution of the build or build to my iOS device the same occurs... 1-4 may have the weird issue depending on screen position etc.
Edit edit: Adding manual padding of 1 to my character sprites seems to resolve the issue, any explination for that?
Edit edit edit: The artist didn't put 1px empty space around the sprites.... I'm going to assume this is best practice and is what caused the entire 4 hour headache. Can you please confirm? I'm going to have him move all the art away from the edges of the image if so.
