fixing alpha textured objects

[joeymax]

Hi there

i have created a tree object in 3dsmax which has a diffuse and alpha texture applied. when i view the object in vizard, there seems to be some problems.

when there is a few alpha textured objects on screen at once they seem to flicker, sometimes they have their transparency, sometimes they dont, and sometimes a grey/white border appears around the object (when that part of the object should be see-through).

I think this has something to do with draworder maybe??

I can send you my scene (along with the textures) but its in a 6mb zip folder (they only let you upload 1mb on here)

Ideally what i want to be able to do is create a scene with lots of trees (2d alpha textured billboards) and i want them to work properly, so that there is no conflicts with other objects in the scene, no pop-ups/flickering etc.
Again.. probably easier to explain if i send you my file.

Thanks
