S.T.A.L.K.E.R. Team Not Art Thieves
Via Kotaku an Inquirer article reports that, despite earlier claims to the contrary, it looks like the folks behind the S.T.A.L.K.E.R. title are not guilty of art theft. It seems both Half-Life 2 and S.T.A.L.K.E.R. use textures from a pack produced by Marlin Studios. The similarities are there because both teams used pre-canned materials for their titles, not because of any tom-foolery on the part of GSC GameWorld.
From the last sentence of the article: "the IMP_Light texture that it was thought could have been pilfered from Doom 3 was, in fact, just a standard Impact Light texture, rather than referring to the Doom 3 monster."
