In Response To: Re: the picture is beautiful (OldNick) : It seems possible that this surface was originally intended to be reflective : and environment-mapped (the effect seen on MC's visor in the first E3 Halo : 2 demo), but was left in an anomalous half-finished state because it's so : far out of the way that only deliberate explorers would ever see it. That : would explain why (a) this particular image is used, and (b) why its UV : setup is near-random. Environment map UVs are dynamically generated : depending on viewpoint, so fixed UV values (which probably exist in every : material data-structure by default, and which would have been initialised : to some extent when the texture was applied to the polygons) would never : normally be used. : Alternatively, the artist texturing this surface simply wanted a texture : which would appear approximately reflective when seen from long distance. : Texture images seen from a distance need to be mip-mapped (have their : resolution repeatedly halved), until the texture resolution is close to : the screen pixel resolution at which they'll be drawn. This avoids : 'crawling pixel' effects, and wasting the GPU's time on undrawable detail. : An image of the surrounding landscape and sky would mip-map down to a blur : of colours which would be representative of those you'd see in a proper : reflection of this environment. In this case, any high-repetition default : UV mapping would serve the purpose, with no need to be careful about : detail or even orientation. uhh yeah, what you said. Interestingly, if I recall correctly, someone extracted the picture from the code, and it's called "containment.jpg," which was evidently the original name of quarantine zone... a name whose rebirth we've just witnessed. Does the picture look anything like the new map? -Sep7imus
