Title: Tiled sprites not tiling properly?
Post by: patrickkidd on August 31, 2013, 03:34:18 PM

Tiled sprites don't seem to always repeat properly. Am I doing something wrong? I'm using the latest NGUI version.

Wow those stripes messed with my eyes.

So, what you're seeing is filtering artifacts. For Tiled sprites, you can get around them by making a 1 px border around the whole thing in PS and add that border to the sprite in the atlas, that way the mesh that gets created cuts away that 1 px border.

I believe that if it's pixel perfect you shouldn't see those artifacts in any case, but I'm not 100 %.

This is due to how texture filtering works. You need to have a 1 pixel border. That is, extend your tiled image by 1 pixel on each side and give it a 1 pixel border within the atlas. Then it will tile correctly without any seams.
