Okay, first things first, is this freeware now? And is it these models here?

I do notice they say FS2002, but the model I have has FS8 in the model header too. I also notice on the same page there is an RF8 too. So maybe a different one, but cannot find a newer one for sale anymore?
Anyway, to add the shine you need to enable reflectivity in the model. This can done a few ways, Hex editing, Scasm editing or by using MDLC by Ivan Hsu/Archisoft. The first two are pretty advanced procedures, luckily the last one is much easier. Download it, read the manual and go. It's a command line proggy, but if that scares you grab Mortons front end for it, mk_MDLC. Both proggies are here in the archives. Once you have enabled reflectivity, you need to add the Alphas to the texs, but you've done that already, hence the transparency.
The later option though easier sometimes has it's own problems, usually with fully reflective gauge plane in the VC, it can be fixed though. Also prop discs and glass can have problems. To fix these requires a simple Hex edit. More on this if anyone gets that far.
The proggies can be found here:
MDLC,
mk_mdlc & a free hex editor,
FRhED.
I do not have the Crusader installed anymore and I fly FS9 (which shouldn't make a difference). I did one model back then, stopped when no-one seemed interested. I intended to do all of them for my own use at my own pace, that hasn't happened as of yet :d I have too many other things to juggle right now to do them, but soon and if they are now Free I may well do them all and upload them, maybeby then you guys will have a native one, lol.
