FatCat is correct that it's shiny, I've use the envmap effect used on the Caddy's tailfins.
Also, the 747 is the large drone from the C2 airport levels (my favourite C2 maps) and it's inside the Eagle because I wanted to test the MDL quickly so just replaced a vehicle part (in this instance, the Eagle-R chassis). This allowed me to test if things worked from the UI rather than having to fire up the game.
And in response to FatCat, nope, no crumple yet. Still working on basic mesh things before getting onto crumple things.
