Was wondering....often had the Orion class in modelview and there's this texture named 'invisible'. After putting the 'invisiblelight' texture in the map folder named as 'invisible' it turns out to be the opening of the fighterbay...so V did a shortcut by using an non-existent texture to fake an opening...and since theres a box behind it with texturing, it really is as if your looking inside the hangar...
sooooo....instead of actual transparancy (so real windows can be used) why not doing it the same way as the Orion fighterbay? if you want to have some reflectance you could use a few very elongated facets as part of that particular mesh area and only texture these with shinemaps, so light can reflect of them?
