First I try to change the texture background color to RED, that display the line in RED color, and when I try to use power of 2 texture, it just same display. http://img839.imageshack.us/img839/6479/qq20120526192922.png
I making a terrain loader, it's works well for loading. In order to better performance, that pack all the textures in one. But now i have a question, all tile textures are displayed the line on the edges. It seems because of wrong texture filtering option, But it just still edges ...
