Alpha Blending problem

Hey guys,

I am making a game in which i am using 2-3 png images on planes and i am positioning those planes on different z-positions, I have used moblie- particles- alpha blended shader on it but the problem comes when I play the game. It seem like the back layer shows at first layer. Its like z-axis issue. Actually I am not able to find a gap between two layers.

Wish Unity had an intro vid that explained stuff like this, this question comes up way too often.

Alpha shaders don’t z-write so they’re not sorted per pixel. This can produce incorrect draw order.

This may help explain it:

Thanx a lot . Its useful.
