If you have ever used textures with alpha channels in your preferred game engine, you may have noticed white pixels around the visible pixels of your textures, specially at far distances. Game engines use several methods such as mipmapping or blilinear filtering to display textures at different sizes on screen. These methods mix transparent pixels with the adjacent visible pixels causing the colors leak through. By default, Photoshop uses white color for transparent pixels, so game engine averages edge pixels with white color of transparent pixels resulting in visibly whiter pixels around the edges. To cope with this problem, we should make sure that completely transparent parts of our texture masked by alpha channel have a color which matches their neighboring pixels. In this tutorial, I use Flaming Pear Free Plugins pack to change the color of masked pixels and fix the white color issue.
