Alpha Texture Problem

I ran into this problem in-Game (with GLSL on). It is two Alpha textures, the green grid far in front of the grey walkway thing. however, the grey walkway appears in front even though it is behind the blue pipe (which is behind the green grid’s base)


A little help on why this occurs and what to do about it would be really really appreciated.

Yeah, that’s because of z-sorting issues. Make one of them use Clip Alpha mode in the Face Textures menu - if the walkway doesn’t have any transparent or invisible parts to it, make it opaque. Alternatively, you could try using the Sort buttons, but they don’t appear to work (at least, to me).
