Unity 3 beta 6 z fighting/depth issue

Unity Engine

I have a a 2D game that had image-planes set apart in z space for parallax and perspective.

They were all rendering fine under unity iPhone 1.5.1f2 but i have upgraded to unity 3 beta 6 and alot of the planes are rendering out of z-order when the camera is panned around across the 2D images.

is this a bug? or is there some new way that unity calculates the zdepth of objects.

i am currently using the particles alpha blended with Zwrite set to On for the shader…

please help if you can shed any light on the matter…

I’ve sorted out the problem so it renders like it did beforehand…

the problem was the alphaTest Greater 0.01 in my alphablended shader

changed it to 0.02 and its all good now… :smile:
