Random gaps between aligned sprites

[SirJson]

Hi,

When I align two or more sprites and then move the ingame camera around I can see sometimes gaps between my sprites. I aligned my sprites with vertex snapping.

When everything is fine it looks like this:


But in the next frame it looks like this:


I already tried the following things:

• http://2dtoolkit.com/forum/index.php/topic,294.0.html
• Point filtering instead of trilinear filtering
• Render Mesh: Diced (with various sizes)
• Increasing / using extra padding
• Disable Trimming
• Custom Render Mesh
• Changing Quality Settings

Unfortunately I have absolutely no idea what is causing these problems... is someone out there who knows how I can fix this?

1. Are you using a perspective camera?
2. Are you absolutely sure the are perfectly aligned? Zoom in really really close to check - I've seen vertex alignment not actually perfectly align things in the past.

Thank you for your quick reply! I didn't check the most obvious reason for that problem. There are indeed real gaps between the sprites...

Is there a better method to align sprites? Vertex snapping seems to be too unreliable.

I usually just a little editor script to do this... a little menu item with a shortcut usually works pretty well - you will want to snap to a grid, or texelSize (sprite.CurrentSprite.texelSize).
