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.
