Everything was converted from Trespasser and the bump maps are just tweaked grayscale versions of the textures. (Trespasser actually used normal maps on some models, but no one has made a converter to convert them into proper images yet. But...normal maps in 1998!
I think the lighting is about right...on bright sunny days with few clouds, shadows tend to be very hard edged and defined and not particulary bright (they're only lit by blue light bouncing off of air molecules afterall...radiosity doesn't really add anything. Just look at pictures on the moon where everything is extremely reflective). Note that the shadows look far darker in the thumbnails then in the actual screens.
Anyway, I did this mainly to inspire people to start some kind of Trespasser mod (not really a direct TC or anything...more like a Jurassic Park mod with a Trespasser-ish spirit) so I probably won't release this level. If people really want me to I probably can though...all the assets are from the Trespasser demo, so I wouldn't think that would really be a problem.
Some of the models have some glitches...the trailer in particular is rather severe. The UV mapping seems to be rather screwed up, it's full bright and other screwed up surfaces show through it. Anyone have any idea what's going on?
