Hmm, this is pretty big... Is STALKER using other game's assets?

One of the first threads to be made regarding the matter was posted to the MapCore forums; the thread creator, user michi.be, posted screen captures allegedly comparing the light image folders from S.T.A.L.K.E.R. to those of Doom 3 (all screen captures locally mirrored). Tellingly, though some of the images had been modified in various ways, such as having hue or saturation adjustments, the original filenames from the Doom 3 folders remained the same--for example, a file with the Doom-esque name "lights_impflash.dds," referring to one of the game's enemies, was visually modified in the S.T.A.L.K.E.R. folder but retained the filename.
