How can I make these drop tanks disappear? Is it through the alpha channel? Is there a tutorial on how to do this?
Thanks for helping,

You need martin Wrights DXT program.
The alphacnannel is basically a greŭscale copy of the texture layed behind the coloured texture.
This greyscale contains the opacity information.
Normally all is visible = alphatexture is just white.
- Find the texture with the droptanks on it.
- Make a copy of the texture, paint all white except the droptank area which is painted black.
- Save as XYZ_Alpha.bmp or whatever.
- Load the original texture with DXT program.
- Load the corresponding ALPHA bmp also.
- Now save the main bmp in a format, that includes the alphachannel feature - DXT1 should do it for you.
(DXT3 does work also, but it will not only blend the droptanks out, but every other part of the plane behind)

It is the SU payware for FS2004. The package comes with several different models. Most of which convert very nicely. Although I can't seem to get their P-38s to convert. Has anyone else had luck with the P-38's from SU?
