In Response To: Re: the picture is beautiful (Sep7imus [subnova]) : Well, it's not a texture glitch in the sense of "two textures next to : each othe rhappen to look like a grunt or somehting if you squint the : right way." : It is a texture glitch in that the background/skymap (I don't know which) is : being used as a texture where it shouldn't be. : -Sep7imus 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.
