I 've been tinkering/researching for the last couple of hours trying to fix the good ol' prop issue of FS9-to-FSX textures.  This old AIA bird that was designed for AI use.  It is all on a single texture sheet with the prop on that.  So I have tried adding an alpha to the whole texture but that doesn't work. Prop is all black.  So I tried just using part of the alpha all white for the aircraft part and then creating a dark gray where the prop texture is located. 

 

Seems to almost work, it is is nice and clear with the scenery behind it but when I see the fuselage behind the prop that portion of the prop is all black.  Is it the way the model was designed?  Am I outta luck?

Thx Dick, for the reply.  I did read that thread before and it did work for one airecraft.  The EMB-120 it would not take so I ended up finding another model that had a separate prop tecture.  That worked for me.  :smile:
