Pixel bleeding - no idea why

Signovinces

Anyone know why i'm getting this problem (see picture)? Nothing is overlapping in Photoshop nor 3ds max but i still get 1-3 pixels bleed from the right black and white plane into the left plane.

I'm trying to make som SCI-FI modular panels and each texture is 512*512 pixels. The atlas for the panels is 2048*2048 and it's very exactly divided into 512*512 pixels large areas. The UV's in 3ds max are snapped with vertex snap so they can't be off (right?). Each plane in 3ds max is a copy of the original one so they are exactly the same size.

Mind that i'm a newbie in the 3d world so this might be a very stupid error/problem on my side.

You need to have space between the elements on the texture, and of course the uv islands as well. The problem is that the texture gets filtered and blurred across that line.

This will become much worse with mip-mapping in a game situation, so you need need a hefty border between the textures.

Any advice as to how large border in pixels, for the textures, should i have?

That was one fine link! Now it makes much more sense.
