Fester,
The films do not do the real time post lighting effects justice. If anything they make the environment look cheezy. I've been building an offline gunnery practice terrain for Ship to Ship, PT to ship, torpedo bomber runs, air spawn to bombing alt, tanker Hogan's Alley, mobile AA, 88mm, 17lb and 37mm using the alpha TE. I think I keep tweeking my cliff faces just to have an excuse to fly around and look at the environment.
I'm betting your last terrain will be incredible when it is upgraded to AHIII.
