Problem with Z buffer in Irredit

[3DModelerMan]

Hi I'm in the process of setting up my scene in Irredit, but I ran into a problem there. I have a tree model with many flat planes for leaves, I import into Irredit, turn off backface culling, set lighting to true, and then modify a few other settings. And I have a problem with what I think is called Z fighting, where some of the faces appear in front of others when they should'nt.
Thanks.

P.S.
I tried searching the ambierra forums but did'nt find anything.

Try to load the scene into an irrlicht app and use the OpenGL renderer. If the scene changes it's a problem with the transparent materials under D3D, which might be fixed soon. Otherwise you'd need a different solution to be discussed.
