Ha, only 42,000? My terrain maps have more brushes, but sadly they also have less complex geometry. If I knew how to carve out caves and shit on terrain I would totally make valleys and caves and shit.
In all seriousness, I've been wanting to convert Shadow of the Colossus - at least some parts of it - to Q3, but reverse-engineering is hard. How do you do your work? Frame dumping, or actual model conversion?
