[Avirtualpilot 2]

Hi to everubody.

I'm making the livery of a Virtual ariline, but I've some problems for the body texture.

Wing, externals and others are ok, but the body appears all black

 

Here my step, what's wrong??

 

first step i set the livery

 

 

Then i purt the livery in the way indicated in the file

 

 

And then i open the bmp with the DTXBmp and i convert it in DTX5

 

 

The body aircraft appears black!!

 

Why???

Thanks a lot
