Angryfly Space Destroyer set

Here is a set of Angryfly's space destroyers i've converted for Freelancer. Don't know why they are called destroyers, as in reality, they are fighters. I added a cockpit to all of these ships with glowing instruments and two pilots, which i borrowed from one of Mancers ship packs and kitbashed it all together.

Thanks, been a while since i messed with some models. Only problem i have now is something we discussed some time ago. When i look through the cockpit, the inside of the model is see through, so i can see say a planet if i'm parked in front of one. There's a setting in MS or something else you told me to do which fixed this, any idea what it was?

Ok, i'm almost there with this now. It's the double sided texture saga. If i type in DcDtTwo into the material library section in the MAT file, this cures the problem. I also want to have an emissive section for some glowing lights on the textures, so normally i would add DcDtEcEt and then that works. Seems i can't have both though. DcDtTwoEcEt, which is what i'm after

*** EDIT ***

DcDtEt - Works with emissive texture, can still see through model
DcDtTwo - No emissive texture, cannot see through model
DcDtTwoEt - Doesn't work, model is completely see through
DcDtTwoEc - Same as above

Am i saving the texture wrong? Thinking out loud for possible causes now. Maybe a setting in Milkshape that i haven't set right?

It's like i can have one but not the other, either DcDtTwo, works fine, or DcDtEcEtTwo which also works but then the interior is see through

Got fed up so no see through cockpit now. This way i can have my emissive textures and everything works ok. Still baffled why it didn't work with a see through cockpit though
