MCX problem with groundpoly.

I am creating ground poly, created a runway using gmax. I have used 8 textures for it such as edge white line, yellow line, overlay, base asphalt and so on. But when I open it in MCX via ground poly wizard, only 6 textures show up.

Then another problem is, I get textures switched, shown in the 2nd picture. The runway overlay. Its supposed to cover only the runway. Not the outside edges. How can I get these 2 fixed? I have the newest MCX version but same result.


I figured it out, MCX doesn't like duplicates. It works this way- create new poly and apply textures individually. If I create a poly, texture it and duplicate that, its not going to work.
Now I got all textures listed in Ground poly wizard and textures don't switch.
