Alpha Map problem.

Can't find the reason for this ?
I have my alpha textures black/white.

One is from the viewport 2.0
One from the UDK ( Works fine )
One from the Hardware Renderer

Ideas why the .... is this happening ?

I checked the alpha illuminance ...

for what I can tell maya always had and still has a problem to display alphamaps in viewport properly when you have overlapping and combined geometry using alpha. this seems to be a sorting or z-buffer problem which means if the geometry is combined maya doesn´t know anymore which plane to render first. this results in flipping textures from back to front and and overall transparent geometry.

here´s a picture to show ->

everything starts and ends in the right place at the right time.

A good way around it is to separate your geometry and assign each peace the same textures and the alpha will just work fine... That's how i do it..
